The major product formed in the following reaction is
The Correct Option is A
Solution and Explanation
The reaction given involves the treatment of the compound with bromine (Br2) in the presence of sodium hydroxide (NaOH) under heat (Δ). This is a classic example of the Hofmann Bromamide Degradation Reaction.
Steps in the Reaction
-
Amide Group Conversion: The amide group (
-CONH2) undergoes degradation in the presence of Br2/NaOH, forming a primary amine (-NH2). -
Retention of Other Groups: The ester group (
-COOCH3) remains intact during this reaction as it does not participate in the Hofmann degradation. -
Formation of the Product: The resulting product is a compound where the
-CONH2group is replaced by a-NH2group, while the ester group remains unchanged.
Major Product
The major product formed in this reaction is:
Cyclohexanone derivative with an amine group (-NH2) and an ester group (-COOCH3) intact.
Key Points
- This reaction selectively degrades the amide group to a primary amine.
- The ester group remains unaltered.
- This is an example of the Hofmann Bromamide Reaction, which is widely used for amide to amine conversion.
