Text Solution

Verified by Experts

The correct Answer is:
B
Acid chloride and acid anhydride are extremely reactive out of acid derivatives. They react independently with water even in the absence of catalyst to give carboxylic acid, which will ultimately reacts with `NaHCO_(3)` to give sodium salt of acid and `CO_(2)` . Ester reacts with water in presence of acid catalyst to produce acid. Acetone is inert toward `NaHCO_(3)` solution.
