Methyl nitrile is hydrolyzed to carboxylic acid in the presence of \(H_3O^+\) as catalyst. An intermediate compound \([A]\) is formed during this reaction.

Converting [A] into [C] is called:

Ammonolysis Hoffmann Degradation reaction Carbylamine reaction Gabriel phthalamide reaction

Hoffmann Degradation reaction

The correct answer is option 2. Hoffmann Degradation reaction. Let us look at the mechanism of the reaction so that we can understand the reaction better:
