Solution
The correct option is C
Carboxylic acid reacts with hydrazoic acid to form amines. This reaction is called Schmidt rearrangement.
Mechanism:
Step 1: Here, carboxylic acid was protonated and water gets eliminated to form acylium ion.
Step 2: Hydrazoic acid attacks the acylium ion to form protonated azide.
Step 3: Abstraction of proton followed by elimination of N2 and aryl group migration leads to the formation of isocyanate intermediate.
Step 4: Formed isocyanate gets hydrolysed to form amine and CO2.
