- Attention! This video about molecular orbitals is much better: • Examples of s-p Mixing...
Alright, let's be real. Nobody understands molecular orbitals when they first take chemistry. You just pretend you do, and then in your next course you learn them a little better. And then a little better than that. And five years later you sort of understand them. So don't get discouraged! Just watch this for a head start and do your best.

Look here! CZcams is deleting all annotations, which I have used in the past to make corrections, so I want to make sure everyone knows that at 0:16, 1:58, 2:12, and 2:40, I say "molecular orbitals" but I meant "hybrid atomic orbitals". Also, for the molecular orbital diagram for N2, the pi 2p bonding orbitals should be below the sigma 2p bonding orbital due to s-p mixing. These are major errors so please make the correction in your head, sorry! I've been much more careful about triple checking my work since these early videos, I promise. UPDATE! This new video about MO theory is much clearer, please watch the new one immediately after this one to get some clarity: czcams.com/video/I2k61JMk71M/video.html
Thanks for great explanation and care for delivering accurate information .
But I have an enquiry about molecular orbitals ... Molecular orbital theory assumes that number of atomic orbitals = number of molecular orbitals , for example in case of formation of H2 molecule there is two atomic orbitals that formed one molecular orbital ( the bonding orbital) , but I can not understand how the other(anti bonding ) orbital is formed .. can you explain it please !
Check out my classical physics tutorials on wave mechanics, the bonding orbital is the result of constructive interference and the antibonding is the result of destructive interference!
Thank you professor
What I didn't get you
Thank you
are you ever so confused that you want to snap the screen off your laptop bc that’s the vibe I’m feeling rn
Lmao I feel that too. I'm studying for the ap chem exam, and I realized that my teacher never taught us this.
same
Tried studying last night nd this comment of yours made my head ache so bad
Familiar to me because I’m insanely stupid.
Samee, my teacher never thought this! I feel like head is gonna burst out rn
"lets start simple" shows crazy diagram
I thought the same thing taking Gen Chem, but now in Orgo, that actually does seem super simple hahaha
Yeah, this was not a good video. He could have explanied what hybradised is
@@J1hn1 If you have no clue what hybridisation is then why are you watching this video?
@@somethingneeddoing021 That is exactly why i am watching it, so i can learn? I think the video could be more educational. Ive learned this now from other sources.
@Jqhn1 i suggest u to watch indian video called Vedantu epic GOC ....It will make you clear
I think I'm going to have to watch this a few times to get it...
Same
Thatsvwhat
Khan Academy's video on sp3 and sp2 orbitals greatly helped me understand the content covered in this tutorial. This tutorial is more of a refresher to solidify your knowledge, so I would definitely recommend watching Khan Academy's video before this one.
@@Mosrodi agree! It's a refresher.
Noob
I used to have an average of 70-80 percent on chem tests. I watched your series for the last test unit (vespr/bonds/shapes/etc..) and got a 98.6%. I couldn't thank you enough for your precise, easy to understand videos. Real heroes don't always wear capes, just beards.
haha awesome! congrats! time to start crafting my origin story
@Jumbo-J1 why be great when you could be PHENOMENAL!
Ooo
and long hair
@@ProfessorDaveExplains Absolutely awesome videos !! Though I'm still at junior highschool, It's easy for me to understand these collage stuffs after watching your video. Thanks for uploading so many nice videos !!!
Online learning is so damn hard, but CZcams teachers are helping me so much. Thank you!
omg you just explained this in 8 minutes much smoother than my prof could in an hour long lecture. I am so grateful for this channel
THANK YOU SO MUCH! you have no idea how much time I've spend researching and trying to understand this! You're such a great teacher! Thanks for doing this for people like us!!!!!!
very happy to help!
Dear Dr. Dave. Thank you for your great lessons. I've learned a lot from your series. This part is very hard and I need to watch this video many times to realize what happened to orbitals when their bond into a molecular form.
Thanks man. one hour lecture has been explained in a 7 minute video. ur great Professor dave.
Jeremy chris17 exactly!
Hey Professor, thanks for all the vids! You just helped me save many hours annotating my textbook meticulously to make sure I have the important concepts down. Especially that one vid with Quantum Numbers. Entire weeks of knowledge summed up in a few mins...
i like the way you worded the description. it gave me some comfort and brought my anxiety level down. thank you
It's amazing that Professor Dave explains this in 7 minutes and gets me understood while my professor discussed mo for 20 minutes and still confused half of class.
Very short and sweet explanations. Good work
You are literally a life saver...I have had multiple breakdowns over this material and was able to learn it in 7 minutes. It seems like it's actually super easy!! Thank you, Professor Dave (you're my hero)!
no cap i had a breakdown thinking about what the nonhybridized lone pairs do and this man saved me 🙏🙏🙏
@@bigboi7140 do they form pi bonds?
Very well explained, thank you! Seems you're going to become a familiar face for me if all your videos are this clear and concise.
Thank you Professor Dave for helping me to understand better, which in turns helps me to teach better. You are a blessing
This is incredibly interesting. I'm glad I'm being forced to learn this for a career working with nothing related to chemistry.
"foRcEd"
@@spiral8138 Ya you are right. I'm not forced to major in the field I want to work in. I can do something else. I hate when people like you use semantics like that. Truth is, I only took chemistry because my department forced all students to take general ed chemistry. It has nothing to do with rounding out our knowledge. It is, in every way, pointless information for this field. It's just another way to milk students for money. Glad I don't have to worry about all of that anymore.
That being said, I did find Chemistry interesting and there are some things I'd like to study more in MY FREE TIME. But charging me thousands to sit through a class where I can't pick and choose what subjects I want to dive into is not interesting to me.
@@daytonasixty-eight1354 Yes I think that certain matter that I learn in school is absolutely pointless and in no way am I going to need this information in life, but I don't complain. The only reason why I don't complain is because despite the fact that this information is useless, learning it makes certain characteristics of our brain stronger such as problem solving. The only thing that needs to be fixed with school is that the field expects you to memorize the content, take a test, and then forget about it.
@@danielborisov5589 I don't think it helps with problem solving at all. Most of our problem solving abilities come from common sense. Much of it genetic. If you are a midwit, you will always be a midwit.
@@daytonasixty-eight1354 There's centuries of research that won't agree with you on that...sorry to burst your bubble.
wow,what a simple and easy explanation . I JUST LOVE TO WATCH YOUR CHEMISTRY EXPLANATION VIDEO " MR.DAVE". DO MORE AND MORE VIDEOS TO HELP THE STUDENTS TO MAKE THEIR CONCEPTS EASIER AND FOR THEIR BETTER UNDERSTANDING. "ONCE AGAIN THANK YOU"
This is literally the only explanation ive found that explains how you can tell how many pi bonds a molecule can have by its hybridization. Thanks!
I know right. For me it is a big issue when teachers just tell you a formula without explaining why or how it works.
crash course orbitals video thats also a good one
@@someone-lo6qk ty :DD
Supremely lucid, engaging, and with vivid illustrations...crucial stuff elucidated with such disarmingly simplicity !! Thanks for the upload...!
Guy at school: I like to study from the textbook
Me, an intellectual: YOU ABSOLUTE 2:15
lmaooooo that actually made me laugh
😂😂 one of the first yt comments to make me laugh
@@kushagrasharma6541 how can it be ONE of the FIRST
@@jonsnow1875 why can't it
@@kushagrasharma6541 It does seem an odd phrase to use if you are merely contemplating “the first” in the sense of one person, above all others, who can be distinguished as the very top of whatever endeavour you are referring to.
I can't believe this education is free!!!.you explain so well! Thank you so much professor dave.❤
This is the best video I've ever seen on this topic. There could easily be a better 1, but you cover the bases nicely. Good job.
You are awesome at tying everything together and having it all make sense. Thank you!
Thank you so much for this. I have been searching for a video to explain the Hybrid orbit theory clearly and you have done just that. Thank you!
Hii
I keep coming back to this video every time I get confused over hybridization questions and safe to say, it works like a charm
woah, thank you sir! this is the first time i really got this, my prof previously was talking too fast that i wasn't able to catch his trail of thought, now i understand it completely thanks!
Your song makes me happy, also your videos have been incredibly helpful to me throughout college. Thank you!
From calculus to chemistry, you have helped me a lot, props!
Probably the best teacher on CZcams. Thank you very much sir.
LOVE THESE! awesome recap material before a final
great conversation stopper (let's talk molecular orbital ) guaranteed to clear the room. the good news , anyone left standing well worth finding out what plannet their from. live long and prosper. great video. thanks.
+Pink John lol, totally agree with you there
+cheers another big plus in knowing this shit ,make us look bit smarter than we are,caution that can bring a whole lot more shit down on our heads. kind regards Aisha Mohamud
Great video and explanations but I think it would be helpful to not only show your answers but your full solutions. Keep up the great work!
Best explaining video ever watched on youtube regarding the topic...Professor Dave...wish you many million subscribers more!!!!
Thank you so so so so so (and infinitely many more so's) much. I have been battling with this for weeks and you made it clear.
Thanks. Really helped a lot to understand these topics. Appreciate your efforts in making it so simple and easy to grasp.
Well, this video easily explains the theories with simplicity. I'm thankful.
You really work very hard and that's why I am your very big fan. Replying to all questions in all videos and after 2 or 3 hours. Hats off to you sir!!!!
hardest working man on youtube!
Definitely sir!
you are pretty great. although i got A's in two semesters of college gen chem and two semesters of organic chem, this was a concept i opted to simply recognize patterns for, and/or general info to answer multiple choice questions for... but never truly "got it" until now. so thanks! love your videos!
You know the proper art of abridging a very large boring topic in a very short and simple video lecture. Salute to you sir!!!!!
Thank you for your help with this initially difficult concept!
You explained hybridization more clearly in one minute than my professor in 50. Thank you so much!
dude, u saved my life
I completely fell off the train for this topic and after watching this I'm feeling very confident in my ability to do this on my exam tomorrow. Thanks for the help and wish me luck!
what grade were you in at the time? I'm curious to know if I'm learning at a correct rate
@@torlarsen2212 I'm learning this in high school. Grade 11 to be specific. WBU?
@@ahmedramadan8885 I’m learning it right now... I’m in grade 11 at the moment
@@rayyan3253 I came from the future to tell you that this came out to be a VERY important topic in chemistry. I'm in a faculty of Pharmacy now, 1st year, and we still learn about these topics as basics.
Wish you luck 🤞
@@ahmedramadan8885 that’s cool bro, thank you and wish ya luck too man
Amazing video! Thanks a lot for your clear and beautiful explanations! One remaining question would be about non-bonding orbitals...How / why do they occur? Thanks in advance!
So ive been watching all your chem videos today because i have an exam tomorrow.And keep singing your intro music to everyone.i think its gonna be my ringtune now.
ooh i should make it a ringtone! good luck on the exam!
Thank You :) It was great.
great man....really appreciating job...thank u sir u really helped me understand hybridization of orbitals
every textbook i read before watching this video confused the hell out of me. thanks for the clarity
I've been so scared of chemistry all semester long until I found this channel kinda by accident. Just wanted to know something about the molecular geometry of one molecule and BAM, basicly a video to every topic I have to understand for my exam. Thank you so much, Dave!
woohoo! please subscribe and tell your friends!
This guy doesn't miss. Still haven't watched any video that wasn't class. Thanks for everything Professor Dave 🙏
I watch the ads so Dave gets paid!
you're my favorite!
oh really
i didnt get any ads ahahaha
Justin Blaha that’s not how it works
And laid
Clear as crystal. Thank you professor!
you are a savior... awesome work... no more complexes.. thank you very much.
it is really a useful video where
the checking comprehension is unbeatable
it is helpful to check our self about our understanding thank u
Nothing like a 2am refresher the morning before an exam lol. Thanks Professor!
I really appreciate your work! Greetings from german chemistry teacher! Keep it up!
my pleasure! please have your students subscribe!
Greetings from Taiwan, too !! appreciated for these nice resources !
Please do consider adding another video on polyatomic molecular orbitals.Great work by the way.
-...and one on monatomic MO that fill pi, sigma, pi*, sigma* (i.e., N_2 and below).-
Oh, that's what v=I2k61JMk71M does. Never mind!
Difficult concept. Great explanations.
YOU ARE AWESOME!! I WISH I FOUND THIS CHANNEL EVEN BEFORE I STARTED ON CHEM!!! THANKYOU SO MUCH!!! You are savior!!! :)
thank you very much professor. although he didn't have complicated animation, i fully understood what he was explaining.
THANK YOU PROF DAVE you helped me out soooo much!
Thank you. Your explanation is much more clearer than my lecturer!!!!
If I could, I would give my tuition to you because you've taught me more in 8 minutes than my professor has in an entire semester.
after learning chemistry for years, all it took was this video to act as the adhesive to bind all the pieces together. ffs thank you
You are heaven-sent; Thanks so much for your dedication.
Wonderful EXPLANATION!!!
It helped me a lot!!!
Awesome explanation! Thanks Prof Dave
you are simply just amazing Dave... keep it up...
GOD bless you...
I think this video made more sense to me than the other one you posted. Thank you so much.
just make sure to read the pinned comment about the errors, this one has an embarrassing amount of them
Amazing.. Thank you professor Dave
THANK YOU! You explained it very well!
VBT was never made simpler! Thank You Professor 🙏
Thank you professor you solved my doubt, in that 2:46 section.... Helped me in visualisation how actually double and triple bonds are formed
omg I finally understood this, thank you!
Very helpful, I now understand pi and sigma bonds rather than just knowing the steps, thank you
my chem exams are in two days. thanks for always bringing quality content!
Excellent video. Thank you!!!!!
Mr Dave you are wonderful in teaching
I love your videos and help me so much in my lessons
Thank you very much 😊 ☺ 🙏 😀
This man explains things better then Feynman. We've got a new Great Explainer in town!
Thank you. Excellent explanations!
thank you so much for making this video
This is extremely clear. Thank you!
Thanks for Great explaination 💕
I can't put into words how good this is...
Like always, best explanation ✌️✌️
Awesome lecture pro Dave
You are a LIFE saver for finals!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You make everything easy
Love u
it,s very help full in my study
I'm brazilian, but your video help me so much...congrats!! Great professor!
It was really a superb explanation
That was so so helpful thank you!
Hey, Im in geology first year and for some reason I have chemistry and this is helping me a lot, thanks Prof
geology does have a lot of chemistry though. how will you know the properties of each rock or it's composition if you don't know chemistry?
Great video professor Dave. I just wanted to mention that not every energy level has s,p and d orbitals. Level one has one 1 s. Level two has one s and 3 p it is starting on the level 3 that d orbitals are present. I took chemistry a long time ago. Please correct me if I am wrong. Thanks for putting in the work to get these great video together.
nope you're absolutely right! i just spoke very generally to give people the foundation, and then when we run through the different energy levels they can see the specific orbitals present for each.
man you are way way way WAY better than Crash Course Chemistry
Thank you so much, now my problem is solved after many days
You're incredibe at explaining complex concepts
GOOD HEAVENS THIS VIDEO SAVED MY GRADE!!! YOU DA BOMB BABYY.
