Question

Choose the correct option. 

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is B

To solve this question, we need to identify the major product formed in the given reaction. The reaction involves an amide group undergoing Hoffmann Bromamide Degradation.

Hoffmann Bromamide Degradation: This reaction is used to convert an amide into a primary amine with one fewer carbon atom. It involves the use of bromine (\( \text{Br}_2 \)) in the presence of a strong base such as potassium hydroxide (KOH).

Reaction Mechanism: The mechanism follows these steps:

1. The amide is treated with \( \text{Br}_2 \) in an aqueous or alcoholic KOH solution.
2. The intermediate formation involves the migration of the R group from the carbonyl carbon to the nitrogen, resulting in a structure with a free amine group.
3. The overall reaction leads to the removal of the carbonyl carbon, leading to a primary amine.

In this specific reaction:

• The reactant is a benzamide derivative.
• The major product is formed by removing the carbonyl group adjacent to the amine and thus forming an aniline derivative.

The correct option shows the primary amine product after removing one carbon atom and retaining the aromatic ring structure.

So the correct answer is:

Hence, option 2 is the major product of the reaction.
