32- PHENOLS

Question 1

How are esters produced? Draw mechanism

Answer 1

> acyl chloride + alcohol –> esters + HCl
- condensation reaction
- nucleophilic substitution
acyl chloride + phenols –> phenyl ester + salt
- heat and base needed
- base + phenol –> phenoxide ion (better nucleophile)
mechanism
(check one-note)
- know how to name products

Question 2

Why acyl chloride is better than COOH when producing esters?

Answer 2

• acyl chlorides are more reactive (produce ester faster)
