Esters and Acyl Chlorides

Question 1

Ester

Answer 1

COOR’

Question 2

Ester naming

Answer 2

Based on its carboxylic acid derivative

E.g butanoic acid →methyl butanoate (methyl instead of acid)

Question 3

Esterification

Answer 3

Carboxylic acid+alcohol →ester+water

Question 4

Hydrolysis types

Answer 4

Acid hydrolysis →carboxylic acid+alcohol

Alkaline hydrolysis →carboxylate+alcohol

Question 5

Acyl chloride features

Answer 5

COCl
-oic acid →-oyl chloride
Most reactive organic compound, so reactions go to completion quickly at low temps

Question 6

Acyl chlorides and nucleophiles

Answer 6

H-Y: nucleophiles react well via addition-elimination reaction
•addition of HY across C=O, then
•elimination of HCl
