The correct order of increasing acidic strength is …..

A

Phenol`lt`Ethanol`lt`Chloroacetic acid`lt` Acetic acid

B

Ethanol`lt`Phenol`lt`Chloroacetic acid`lt` Acetic acid

C

Ethanol`lt`Phenol`lt`Acetic acid`lt` Chloroacetic acid

D

Chloroacetic acid`lt`Acetic acid`lt` Phenol `lt` Ethanol

Text Solution

Verified by Experts

The correct Answer is:
C
Due to-I effect of chlorine, chloroacetic acid is a stronger acid than acetic acid. Further, due to stabilization of phenoxide ion by resonance and no such stabilization in case of ethoxide ion, phenol is a stronger acid than ethanol. Thus, the overall acid strength follows the order:
ethanol `lt` phenol `lt` acetic acid `lt` chloroacetic acid.
