Question

In the given reaction sequence, the structure of Y would be:

• A.
• B.
• C.
• D.

Hint:

For reactions involving diazonium salts, the resulting product often undergoes electrophilic aromatic substitution. Keep an eye out for functional groups like NO$_2$.

Answer 1

The Correct Option is B

Aniline (C$_6$H$_5$NH$_2$) reacts with sodium nitrite (NaNO$_2$) and HCl at low temperatures to yield a diazonium salt intermediate. This intermediate subsequently reacts with phenol (C$_6$H$_5$OH), producing a nitro derivative (NO$_2$). Consequently, product Y is the nitro derivative of the benzene ring.
