COMEDK · Chemistry · 29. Amines
The amine which will not liberate nitrogen with nitrous acid is
- A ethyl amine
- B methyl amine
- C dimethyl amine
- D 2-amino propane
Answer & Solution
Correct Answer
(C) dimethyl amine
Step-by-step Solution
Detailed explanation
Only aliphatic primary amines react with nitrous acid to give alcohols with the evolution of \(N_{2}\) gas. \[ R-\mathrm{NH}_{2}+\mathrm{HONO} \stackrel{273-278 \mathrm{~K}}{\longrightarrow} R-\mathrm{OH}+\mathrm{N}_{2}+\mathrm{H}_{2} \mathrm{O} \] \(\because\) Dimethyl amine is…
