Question:
The major product Z formed in the following sequence of reactions is:
$$ {C2H5Cl →[AgNO2] X →[Sn/HCl] Y →[(i)\ NaNO2][(ii)\ HCl,\ H2O] Z} $$
The major product Z formed in the following sequence of reactions is:
$$ {C2H5Cl →[AgNO2] X →[Sn/HCl] Y →[(i)\ NaNO2][(ii)\ HCl,\ H2O] Z} $$
Show Hint
Alkyl halide with \(AgNO_2\) gives nitroalkane, nitroalkane on reduction gives amine, and primary aliphatic amine with nitrous acid gives alcohol.

The Correct Option is D
Solution and Explanation
The major product Z formed in the following sequence of reactions is:
$$ C_2H_5Cl \rightarrow[AgNO_2] X \rightarrow[Sn/HCl] Y \rightarrow[(i)\ NaNO_2][(ii)\ HCl,\ H_2O] Z $$
- Initial Reaction:
Ethyl chloride (C₂H₅Cl) reacts with AgNO₂ to form a nitro compound:
X = C₂H₅NO₂ (nitroethane) - Second Reaction:
Reduction with Sn/HCl converts nitro compound into amine:
Y = C₂H₅NH₂ (ethylamine) - Final Reaction:
Ethylamine reacts with NaNO₂ in acidic medium (HCl/H₂O) to form an unstable diazonium intermediate which decomposes to alcohol:
Z = C₂H₅OH (ethanol)
Thus, the major product Z is: C₂H₅OH (Ethanol)
