MCQChemistry

NCERT · Class 12 · Chemistry · Aldehydes, Ketones and Carboxylic AcidsWhich of the following acids is the strongest?

Step-by-Step Solution

Chloroacetic acid is stronger than acetic acid due to the -I (inductive) effect of the chlorine atom, which stabilizes the carboxylate anion by dispersing the negative charge. Formic acid is stronger than acetic acid, but trichloroacetic acid is even stronger than monochloroacetic acid due to three chlorine atoms exerting a stronger -I effect.
