Question

In the following reaction sequence, what are X and Y respectively? 

• A.

  

• B. \( \text{NH}_2\text{NH}_2 ; \, \text{Zn-Hg}, \, \text{HCl} \)
• C.

  

• D. \( \text{NH}_2\text{OH} ; \, \text{Zn-Hg}, \, \text{HCl} \)

Hint:

The Wolff-Löffler reduction can convert esters to hydrazones, followed by base hydrolysis to yield amines.

Answer 1

The Correct Option is A

In this reaction sequence, the starting material is an ester (ethyl acetate, C6H5COOCH3). The first step involves hydrazine (NH2NH2) reacting with the ester, which undergoes reduction to form hydrazone (X). Subsequent treatment with KOH or water hydrolyzes the hydrazone to form the corresponding amine, which is the final product (Y).
