C

D

Chloroacetic acidltAcetic acidltPhenolltEthanol

Text Solution

Verified by Experts

The correct Answer is:
C
Due to -I-effect of Cl, 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 increases in the order: ethanolltphenolltacetic acidltchloroacetic acid.
