Question

For the reaction:

The correct order of set of reagents for the above conversion is :
 

• A. \( \text{Br}_2, \text{FeBr}_3, \text{H}_2\text{O}(\Delta), \text{NaOH} \)
• B. \( \text{Ac}_2\text{O}, \text{Br}_2, \text{H}_2\text{O}(\Delta), \text{NaOH} \)
• C. \( \text{H}_2\text{SO}_4, \text{Ac}_2\text{O}, \text{Br}_2, \text{H}_2\text{O}(\Delta), \text{NaOH} \)
• D. \( \text{Ac}_2\text{O}, \text{H}_2\text{SO}_4, \text{Br}_2, \text{NaOH} \)

Hint:

Electrophilic aromatic substitution of amines typically requires the use of halogenating agents like Br\(_2\), activated by FeBr\(_3\), and an appropriate base like NaOH for the reaction to proceed smoothly.

Answer 1

The Correct Option is A

The given reaction represents the bromination of an amine group, likely to form an amine derivative, with Br\(_2\) under the influence of a Lewis acid such as FeBr\(_3\), and the reaction is carried out in the presence of NaOH to neutralize the acids formed. The major product obtained in this process follows electrophilic aromatic substitution.

Final Answer: Option (1).
