I found your channel only few days before my exam and I felt I was going to be doomed before but I’m saved by your VDOs! Thank you for all these wonderful works. Your teaching really helped me put everything in one piece and make them easier to memorize. My only regret is that I should have found your channel sooner ; - ; will surely recommend your channel to my junior. Thank you so much!

Hi Leah! I'm a Chemistry tutor in Singapore and have just started out on creating Chemistry videos on my Channel to share with my students. I find your Organic Chemistry videos really useful and I have featured your Channel on mine. Hopefully you are cool with that! I'm really inspired by KZread educators like you who have reached out and helped so many chemistry students in the world! Please continue to create more videos. Will look forward to them. Cheers! Best regards, Maverick

Hello, to go from an acid halide to an anhydride can't you use a regular carboxylic acid to attack the carbonyl and have it be deprotonated by water or something else? Or do you need to use a deprotonated carboxylic acid instead?

@Leah4sci

6 жыл бұрын

HCl is a strong acid and will react with and destroy the anhydride

Perhaps I missed something, but are soaps a part of the carboxylic acids or derivates? I have them together as a subject in my Org.Chem class. Thanks for the great videos!! Your explanations are very helpful and give me some hope for passing this course! (P.S. I met with a tutor and showed them your flip rule for enantiomers and the aromaticity "monster" and he thought they were great!)

Hi Leah! I'm confused about what you mean about making something more reactive (9:07) the less reactive group will get us there. Wouldn't it be the Amide reacting to make an ester or anhydride? Since the Amide is the less reactive out of them all. Thank you!

@Leah4sci

5 ай бұрын

Oh wow I misspoke, the MORE reactive group will react to give you the less reactive derivative. I had it backwards, thanks for pointing this out

Leah if you react ammonia with the carboxylic acid, won’t it protonate the ammonia which makes a non-nucleophilic ammonium ion?

@Leah4sci

Жыл бұрын

Correct. You would have to follow this specific reaction with heat in order to get the amide. For more detailed help with this reaction and others, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/

I like to think of R as the "REST" of the molecule. It represents a variable group, other than the part of the molecule we are focusing on, at the moment.

Why is there no mention of aldehydes? Are they not a derivative?

@rainmelodiess

Жыл бұрын

aldehydes aren’t a carboxylic acid derivative, because hydrogen isn’t a particularly great leaving group. carboxylic acids generally have good leaving groups on their alpha carbons (the carbon next to carbonyl carbon). aldehydes are a carbonyl however, just not a carboxylic derivative.

@Leah4sci

8 ай бұрын

Aldehydes have a H next to the carbonyl which is not a good leaving group nor easily formed from a carboxylic acid
