Just a quick Esterification mechanism, an ester is formed from a carboxylic acid and an alcohol with a strong acid used in a catalytic amount.

You made the whole mechanism quite clear. Thankyou :)

I agree with the others who have mentioned it, you are showing a CH3 in the middle of a molecule which should be a CH2, I'm learning this and got a bit confused for a second.

Peace be upon you Why put CH3 where it should be in CH2Please I want to clarify

@ChommyK 13 жыл бұрын

Just a minor correction: it's HO-CH2-R, not OH-CH3-R

thanks for that. but to be honest, it might be a good idea to redo the video due to the amount of errors. mobile viewers cannot see the annotations, which can further confuse things. but I got it! so thanks for the video :)

what would happen if i'll use tertiary alcohol in esterification? Are there any difference between primary alcohol and tertiary alcohol in esterification?

@ipshitatandon5134 3 жыл бұрын

Yes there is! Esterification with tertiary alcohols is much slower than that with primary and secondary. This is because alcohols here are acting as nucleophiles; and more bulky is the nucleophile, more difficult it is to attack ! Also, tertiary alcohols, in the present of a strong acid catalyst undergo dehydration reaction (due to the formation of a stabilized carbocation), which is much faster than esterification. Thus, the order of reactivity is : ch3oh > 1 deg > 2 deg > 3 deg

Well...the CH2.

in alcohal attack carbon form 5 bond which is incorrect .it is HOCH2R. not HOCH3R

how does H2SO4 make an hydrozonium ion?

Hey I put a not on the video where this error is!

Yep whoops I think I misunderstood. Just added some annotations now.

@JaysanJanabel 12 жыл бұрын

@d00bleA But sir, @ChommyK also implied that the carbon cannot have 5 bonds. Alcohol should be HO-CH2-R indeed. This can confuse some students pretty much. However, still brilliant explanation! Thanks!

Yes, it is Rch2oh rather than Rch3oh👍.
