Reaction of C2H5NH2 with HNO2
The reaction of C2H5NH2 (ethylamine) with HNO2 (nitrous acid) is an example of a diazo reaction. The reaction proceeds as follows:
Step 1: Formation of diazonium salt
HNO2 reacts with ethylamine to form the diazonium salt, C2H5N2+:
C2H5NH2 + HNO2 → C2H5N2+ + H2O
Step 2: Decomposition of diazonium salt
The diazonium salt decomposes to form ethanol and nitrogen gas:
C2H5N2+ → C2H5OH + N2
Therefore, the correct answer is option A, C2H5NH2 produces C2H5OH on reaction with HNO2.
Explanation
The reaction of C2H5NH2 with HNO2 is an example of a diazo reaction, which involves the formation and decomposition of diazonium salts. In the first step, HNO2 reacts with C2H5NH2 to form the diazonium salt C2H5N2+. This intermediate can then undergo decomposition to form the alcohol C2H5OH and nitrogen gas. The reaction is commonly used to prepare alcohols from primary amines, and is a useful synthetic tool in organic chemistry.

Nitrous acid is a source of electrophilic nitrosonium ion (O = N+), which reacts with primary aliphatic amines to form diazonium salts, which are unstable and liberate nitrogen to form a carbonium ion, which in aqueous reaction medium forms an alcohol.
