Good to know someone else is here. Omg I am literally crying because of this exam I have in 4 days and I CAN'T understand aldehydes and ketones AT ALL
@lona3763 lol I have the final after 2 hours, and I really don't know what is happening here
F chemistry
I CAN UNDERSTAND THE CONCEPTS BUT I CANT UNDERSTAND THE CONCEPT.
Even if u understand u are bound to forget in exam hall. No other way other than memorizing it.
Bro going insane like me 🗣️💯
@@vlvt-thingsLMAO ME TOO
@@vlvt-thingsall of us dude 💀😭
That's what happens to me@BLED555
I just want to say you are absolutely amazing and you have helped so many students. Your videos are always prefered over Khan Academy for me!
for me also
Same
@@edmhouse5273
.
Respect Khan Academy, it's totally free, and deals more with explaining than examples
Best organic chemistry content on youtube. I used your videos as supplementary materials and got an A in Orgo 1 and currently have an A+ in orgo 2.
شلون يمعود 😢شنو الطريقة
عرفتي خبريني؟؟؟؟ @@NoorNoor-pf5id
A+ is organic chem 2 is actually crazy. good job!
@@user-cy1jk5ly3xno, not really.
Thank you man. Much appreciated, I didn't do chemistry last year and skipped an important year in High school but just picked up again and found it really hard. This is so helpful.
Currently prepping for the MCAT, and this video is gold
Some important condensation Reactions of Carbonyl compounds
1.Aldol Condensation - a,b unsaturated carbonyl compound
2.Claisen ester condensation - B-keto ester or 1,3diketones
3.Perkins addition - a,b unsaturated carboxylic acid
4.Knovenegalal addition -a,b unsaturated carboxylic acid
5.Wittig reaction - Alkenes
6.Cannizaro reaction - Alcohol and sodium salt of Carboxylic acid ( Redox reaction)
7.Michael addition-1,5 dicarbonyl Compund
8.Mannich reaction - B amino carbonyl compound
only tonight i have learnt of your channel and so far it has helped me greatly
thanks alot for everything you're the reason m acing my organic,physics and maths class....please post a video on differential equations and its applications
I'll be writing my mid term exams on 22rd APRIL 2022 and your the only one that's gonna help me out 😅🤞✊
really helpful for my major course, feel really grateful for this lesson
This is everything I need rn. You are so loved homie
I have greatly been helped you are the best
Thank you !. It's became more helpful for me .I want to know the mechanism of propanone heated with hydrazine in the presence of glycerol.If it would possible to share about it.
Really helpfull and well explained
Soooo helpful! Thank you!
Hi! I have been reading on organic chemistry reactions too, I wondered, is the Wittig Reaction actually stereospecific, and for non-stabilised ylides, they will form cis alkenes, and for ylides stabilised by EWGs such as carbonyls and also nitriles, the trans alkene is formed. But great video, learnt a lot from this channel over the years
You are so amazing.l really appreciate you
Can sodium carbonate react with a ketone and what would be the result of the reaction? Thanks
please i confused a lot about enol formation & aldol condensation.
1.) carbonyl when attack by nucleophile like amines, nitriles and importantly OH(alcohol) they all attack at carbonyl.
2.) then why in enol formation strong base like NaOH (-OH) attack the alpa-H that doesnt make any sense... since alpa-H also exist in other nucleophilic attack (nitrile,alcohol,etc).
3.) when enol formed then continue in aldol cond, why it is considered attack its original form (aldehyde,ketone)???
4.) iffffff thats the case, why it wont happen in other reaction e.g imine from ketone will attack ketone again perhaps to form somethin else??
Your video are really helpful
doesn't the reaction of a ketone/aldehyde with a grignard reagence also work with H2O in replacement for the H3O+ due to the positiv partial charge of the H-atom within the water molecule ? you would get an alkohol and MgBrOH
Do you have videos on naming cycloalkenes
you're the best!!!!
45:20 I've got no idea bruv
Life saver!
not sure if you will reply but at about 7:20 you have the BH4 that reacts a second time? Why is it BH4 reacting? A hydrogen was already taken from the BH4 so should it it be BH3? correct me if I am wrong
It’s another NaBH4 ion
Rutgers should send the organic chemistry tutor all my tuition money :)
Hoping you'd get 1M+ subs soon.
he got 2M+
He has 4M+
Its 5.72 now
But i think in 1:11, in final product CH3 group have missed
Anyone want to take my exams? 😔😔😔 ughhhh don’t wanna fail
Btw your videos are amazing it just never clicks for me when I see a weird structure I get thrown off
9:47 what if we add two equivalent LiAl(OR)3H to chloride acid? Will the extra reagent reduce aldehyde ?
Yes
This is also my question
It depends on the relative electrophilicity of the two groups. In this case the -Cl is more reactive than the aldehyde so it does the single addition to all Cl first. However if you added more it will keep going. If the initial carbonyl is an ester, the reagent will do a double addition to go all the way to the alcohol because the aldehyde will be more reactive.
58:30 wouldnt the cyclohexane expand its ring to become a lactone?
yeah, that is what i was thinking too
1:11:45 penultimate mechanism missing methyl group attached to OH carbon?
yes
time stamps would be really helpful :(
this is a good video lessons, but still i dont understand, thankyou, god bless
i agree with u
Studying organic chemistry makes more and more matchstick man appear in my head 😂
Really helpful lecture sir, Thank You
Addition-elimination e.g. aldehyde or ketone with 2,4-
dinitrophenylhydrazine. How mechanism looks
1:11:53 did you forgot the methyl group?????????
definitely did. no disrespect to sensei ofc, just saying
perfect
I learn from your videos and understand it all but as soon as I get to my fucking test or homework the mechanisms are 10 steps long and physically impossible unless you have a phd in this bs
Just wanted to comment at 39:15 that is not an acetal that is the hemi acetal form, you need to react it again with the Ch3 group to create a full acetal
Can you suggest me the best book for organic chemistry
Organic chemistry by Paula yurkanis bruice
Alright Mr organic tutor
Content is boring but you did save my grade 😭. Better than what my professor explains not gonna lie and even though it's from 4 years ago.
24:35 what is HB???
It’s any base (B) with a hydrogen (H)
Watching your video I don't need text book because I have mobile teacher with me
45:20 legit lol'd
34:00 not an acetal it's a ketal thank you
Cant understand

In this video
YYYAAAWWWWAAAAAA!!!!

I love you 💔💔💔

Gusto ko nalang maging kamatis😫😭
… . .. .. .. .. …
Omg, chemists good luck
After spending an hour with you. No "thank you" "see you later" "have a nice day"? What sort of lecturer are you 😏
😂😂😂😂😂😂😂😂😂
The one that gives u information ur lecturer cant 😊
you are my lord and my saviour, i pray to you every night before an exam, i offer you sacrifices by burning dead flies and smelling it
Really really good explanation but there's a serious problem that you're a bit fast even i slowed it down that was not enough :(
Really? I usually watch his videos at 1.5x speed because i felt he's slow sometimes.
@@dominiccenteno1233 same here
Dominic Centeno he is too fast for me
maybe because either i’m not native or i suck at chemistry
Well I watch it at 2x .. Pray for me
You are too fast big man
Not good
