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

This reaction involves the bromination of an amine group, producing an amine derivative. The process utilizes \(Br_2\) with a Lewis acid catalyst like \(FeBr_3\), and \(NaOH\) is present to neutralize generated acids. The primary product results from electrophilic aromatic substitution.
Final Answer: Option (1).
