Ohh my god 😭😭😭😭... I'm so happy seeing your video after long time .... Please do as more topics as you can ... You are the only one who can make me understand complex topics in chemistry ❤️❤️...i am very very much thankful to you ❤️❤️❤️... I love you sir you are the best ❤️❤️❤️❤️❤️
I love your positivity and I agree, this CZcamsr is quite helpful!! Also please don’t use the Lord’s name in vain, just a suggestion :). Have a blessed day!! and good luck in your classes!!
I've been out of college for a half decade and come back to this channel just to learn new things or brush up. That's how good this stuff is! DeWitt, your still killin' it my man!
Hi Mr DeWitt! You have helped me perform very well in Chemistry this year, and I just wanted to tell you how much I appreciate your help for every single topic! :) I'm really glad to see you now as I've been watching your videos that were released 7-10 years ago. I truly appreciate it! :D
I feel like you practically added a few more years to my life with these videos man. You make this stuff so easy to understand. I can't thank you enough.
Hi ty, i learnt the chemistry from scratch by seeing your videos now after i read my class 11 book, the feel of understanding is just awesome man.... thanks a lot..
Omg I needed this. Also i actually went to your website and got the sample test and answers, and that was so worth it!! The information is going on flash cards ASAP.
You are such a great teacher I found on the last minute of my test and passed in electrochemistry I'm really really glad to find you your teaching amazes me like I used to hate chemistry and after finding you I was just like that how a subject can be sooo fun will you please explain organic chemistry from basic it's my humble request please????
Thank you so much for your help! I'm really nervous about my upcoming test on Monday, but your recent videos have given me so many last-minute tips. I feel so much more confident now!
AP Chem? I'm in basic Chemistry 1 and have to know all this, which sucks since I'm just trying to go for a mechanical engineering degree. But do really appreciate all your videos!
Could you make a video on Lewis Dot structure? you explain stuff the best out of any CZcams channel video or teacher I've every had or anyone friends whoever that has taught me chem ever. Thank you.
For the IMFs question, is it necessary to mention how both methanol and formaldehyde also have LDF attractions with the polarizability of their electron clouds? I heard that you should always mention all types of IMFs on the AP exam
Thank you so much! You have saved me twice already just in the past two weeks. However, just one question - for 5:07, why is it not Bent, like H2O? The O in H2O also has 2 single bonds + 2 lone pairs, but H2O would be bent and
Well the bond in H2O is about 105°. Yes it is a bent geometry, but it is based on a tetrahedral geometry, which has a 109.5° bond angle. So yeah, if those electron pairs didn’t repel so much, it would be 109.5°, and 105° is close enough that the difference doesn’t matter for the test.
8:52 shouldnt it only be H bonding because mentioning hydrogen bonding implies that dipole-dipole interactions are present, as hydrogen bonding is a subset of dipole-dipole interactions
In water molecule H2O.. oxygen has two bond pairs and two line pairs… just like C-H-O… so shouldn’t it be a V shape and the bond angle should be 104.5?
Right, and that’s why I said “the bond angle is a little less that 109.5°, but for the AP Exam you just need to know the approximate value, and 109.5° is fine.”
Yes and no. The actual angle depends on the identity of the atoms. Sometimes it’s 104.5, sometimes less, sometimes more. It’s not *always* 104.5 in this case. However, the ideal theoretical is 109.5, which is why it’s acceptable to say 109.5, or “slightly less than 109.5.”
@@birdie7344 i finished it half an hour ago. I think it went well considering i did not study much. Most importantly, there were many similar questions to the ones in these videos.
@@tdewitt451 you are so welcome. Last semester I took chemistry 121, I was so lost and In dispare. I got a tutor, and also watched your videos. Between the 2, I got a B in the class. Do you have microbiology videos, as well? I’m taking micro 250 this semester. Final is in a week, but I wouldn’t mind turning my B, into an A.
No one will replace Mr.Dewitt teaching... Such a Nice explanation in detail
FACT.
It is currently dark outside and I was stressing about my test tomorrow! You, sir, are freaking amazing! Thank you so much for the help!
I’m so glad you’re back doing videos! You’re a chemistry treasure 💎

I love these glad to see you are uploading new videos. I just started taking chemistry again and your videos always help. Thank you for everything :)
Just took the AP test, and your videos were great help! Thank you!
Thank you very much professor!
I've been watching your videos since 2015...
omg. im done all my chemistry uni courses now but im so glad this guy is back on youtube!!! definitely the reason i survived university
You are back!!! I remember watching your videos on what moles are in grade six and now watching this for A2 Chemistry!
I hope it’s helpful!
Probably the best chemistry online tutor"
You're such a vibe. Glad you're back. Watching your videos has been a plus to me
Never seen a teacher like you i love so much of your teaching
Sir, my daughter so GRATEFUL for your such amazing teaching!! THANK YOU THANK YOU THANK YOU! 🙏🌷🌷🌷

Hey man, thanks for existing
You're back! I missed you!
Ureka!! Mr Tyler is back!!
Thanks for these videos!
Crystal clear explanation
Thanks from INDIA 🇮🇳
How good this channel is, i'm the chemistry student at university
thank you for this series
Thank you so much Sir. Lots of love...
Omg, I just discovered you returned to CZcams!
OMG HE IS BACK THANKYOU
Thanks a lot sir... Keep posting more videos...
My best facilitator ever
Thanks Tyler, very nice.
He’s back!!!
I hope, you will make more videos for us. Thanks so much.
AP Chem? I'm in basic Chemistry 1 and have to know all this, which sucks since I'm just trying to go for a mechanical engineering degree. But do really appreciate all your videos!
You are the best 👌
Thank you for helping me throughout my exams!
You're a nice teacher than my teachers. Lols, they didn't explain the whole thing they just gave an assignment to us.
Could you make a video on Lewis Dot structure? you explain stuff the best out of any CZcams channel video or teacher I've every had or anyone friends whoever that has taught me chem ever. Thank you.
I take mine today.. thank you
Sir you really made chemistry easy
Best teacher out there oh my goodness
OMG YOU ARE BACK
Please need an explanation on Bohr's model as it becomes very hard to understand quantized energy and angular momentum. Thanks in advance.
You're our hero ⭐
Thank you sir...
thank you so so much!
I already graduated I just love watching these videos
gracias por existir
He's the goat of physics
Taking mine in an hour. TYSM for your help
Good luck!!!
@@tdewitt451 Update: I got a 5! Thanks for your help btw
Ur unique sir 🙏
Sir, could you make a lecture on "Le Chatelier's Principle". Plz
😍I feel the chemistry between us
Very nice👍
Saved my life
Can you make a video on molecular orbital theory and postulates Mr Dewitt?
Thank god for Tyler
The lone pairs in formaldehyde is not counted???
Thank you sir so much. Can you do about enthalpy too
can we use uranium U238 or Thorium as anode electrode in a battery ? to make battery 🔋 with 22,394,000,000 Wh/kg energy density?
Good video
I hate chemistry thanks to my teacher, only reason I subbed this guy is the most amiable way in which he explains.
For the IMFs question, is it necessary to mention how both methanol and formaldehyde also have LDF attractions with the polarizability of their electron clouds? I heard that you should always mention all types of IMFs on the AP exam
You don’t need to there, because the LDF’s really aren’t relevant for explaining the *difference* in boiling points. But great question.
Thank you so much! You have saved me twice already just in the past two weeks. However, just one question - for 5:07, why is it not Bent, like H2O? The O in H2O also has 2 single bonds + 2 lone pairs, but H2O would be bent and

@@tdewitt451 I see. Thank you so much for the thorough explanation!
sir please make a video about gibb's free energy and ionic equilibrium......that would be very helpful
8:52 shouldnt it only be H bonding because mentioning hydrogen bonding implies that dipole-dipole interactions are present, as hydrogen bonding is a subset of dipole-dipole interactions
Hey teacher, I really need videos about electrochemistry (conductivity, molar conductance and etc…) please help me.
Thanks 💚
Make a video on how to find no of isomers ?
About 3 months to late for me but still, thanks for making these.
In water molecule H2O.. oxygen has two bond pairs and two line pairs… just like C-H-O… so shouldn’t it be a V shape and the bond angle should be 104.5?
Right, and that’s why I said “the bond angle is a little less that 109.5°, but for the AP Exam you just need to know the approximate value, and 109.5° is fine.”
3:44 shouldn't it be bent(104.5) since it has 2 lone pairs and 2 bonds?

Please make a video on HYBRIDISATION...
We have polar and dipolar concepts video
. Pls put on the video
Please can you make videos on titration and back titration
Hey can anyone recommend any AL physics teaching videos available in youtube
WE MISSED YOU!
One day before the exam, thank you
tell us how it goes tomorrow!
@@birdie7344 i finished it half an hour ago. I think it went well considering i did not study much. Most importantly, there were many similar questions to the ones in these videos.
Where was this when I had Ochem finals last week?
Please continue your channel on mot
please do a video on solubility rules!!
and ksp and all that good stuff, just a suggestion. !!
You are so awesome!
thank you hahah
yes i know
