Vedclass · Accepted Answer

$N, N$-Dimethyl ethanamine

Vedclass · Answer

(D) Primary aliphatic amines $(R-NH_2)$ react with nitrous acid $(HNO_2)$ to form unstable diazonium salts,which decompose to evolve $N_2$ gas.Secondary amines $(R_2NH)$ react with $HNO_2$ to form $N$-nitrosoamines (yellow oily liquids).Tertiary aliphatic amines $(R_3N)$ form water-soluble nitrite salts with $HNO_2$ but do not undergo the characteristic diazotization or nitrosation reactions that evolve gas or form distinct oily layers like primary and secondary amines.Among the given options,$N, N$-dimethyl ethanamine is a tertiary amine $(CH_3CH_2N(CH_3)_2)$,which does not react with nitrous acid to form a stable product or evolve gas in the same manner as primary or secondary amines.
