Q. The amine which will not liberate nitrogen on reaction with nitrous acid is
A) Trimethyl amine
B) Ethyl amine
C) Sec-butyl amine
D) t-butyl amine
Explanation
(a)
Trimethyl amine is a tertiary amine. It dissolve in cold nitrous acid to form salts which decompose on warming to nitrosoamine and alcohol. It will not liberate nitrogen.
$\left( CH_{3} \right)_{3}N + HNO_{2} \rightarrow \left\lbrack \left( CH_{3} \right)_{3}NH \right\rbrack^{+}NO_{2}^{-}$
trimethyl ammonium nitrite
