Question

"A" in the below reaction is: (Note: Reaction scheme is missing from the provided text)

A

Cu2Cl2Cu_2Cl_2

B

H3PO2H_3PO_2 and H2OH_2O

C

H+/H2OH^+ / H_2O

D

HgSO4/H2SO4HgSO_4 / H_2SO_4

Step-by-Step Solution

Although the specific reaction scheme is missing from the provided text, based on the correct option and the subtopic of diazonium salts, 'A' represents the reagent used for the reduction of a diazonium salt to the corresponding arene (e.g., converting benzene diazonium chloride to benzene). Hypophosphorous acid (H3PO2H_3PO_2) in the presence of water acts as a mild reducing agent, replacing the diazonium group (−N2+X−-N_2^+X^-) with a hydrogen atom, while getting oxidized to phosphorous acid (H3PO3H_3PO_3).

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Amines. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
