The carboxylic acid of least acidic strength among the following is

A

p-Nitrobenzoic acid

B

p-Methylbenzoic acid

C

p-Chlorobenzoic acid

D

p-Methoxybenzoic acid

Text Solution

Verified by Experts

The correct Answer is:
D
Electron donating groups decrease acid strength of benzoic acid and electron withdrawing groups increase acidic strength . Order of `+I` effect is -Ome `gt` -Me, so, p-methoxy benzoic acid is weaker acid than p-methyl benzoic acid.
