Question

The gas evolved when methylamine reacts with HNO\textsubscript{2 is:}

• A. NO
• B. N\textsubscript{2}
• C. NH\textsubscript{3}
• D. NO\textsubscript{2}

Hint:

The reaction of amines with nitrous acid often leads to the evolution of nitrogen gas and the formation of alcohols or other products.

Answer 1

The Correct Option is B

When methylamine reacts with nitrous acid (HNO\textsubscript{2}), nitrogen gas (N\textsubscript{2}) is evolved as a result of the diazotization reaction. This reaction is typical for primary amines.
