Chemistry - Carboxylic acid and their Derivatives Question with Solution | TestHub

Question Explanation:

Identify the correct statements regarding the mechanism and intermediates of the Hofmann Bromamide Degradation for a substituted benzamide.

Concept:

This is based on the mechanism of the Hofmann Bromamide Degradation reaction. Solution:  

The reaction involves the conversion of an amide to a primary amine via an acyl nitrene intermediate (III'), as shown in Option (1). 

The Rate Determining Step (RDS) is the migration of the alkyl or aryl group (para-tolyl group in this case) from the carbon to the nitrogen atom to form an isocyanate (IV).
