Question

The major product formed in the following reaction is

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is A

The given reaction involves a compound undergoing Hofmann Bromamide degradation in the presence of bromine and sodium hydroxide (NaOH).

Mechanism: Hofmann Bromamide degradation is a reaction where an amide is converted into an amine with one carbon less than the original amide.

1. The initial substrate contains a CONH₂ group, which is characteristic of amides.
2. In the presence of Br₂/NaOH and heat (Δ), the degradation occurs as follows:
   • The amide group undergoes decarbonylation, losing the carbonyl (CO) group as CO₂ gas, resulting in the formation of an amine.
   • This reduces the carbon chain length by one carbon atom.

Applying this general knowledge to the specific problem, we focus on the transformation of the CONH₂ group.

Conclusion: The Decarbonylation leads to the major product being the corresponding primary amine with the reduced carbon chain.

Hence, the major product formed in this specific reaction is:

The correct answer is therefore represented by the above structure.
