Vedclass · Answer

(D) Primary $(1^o)$ aliphatic amines react with nitrous acid $(HNO_2)$ to form unstable diazonium salts,which decompose to evolve $N_2$ gas: $RNH_2 + HNO_2 \rightarrow ROH + N_2 + H_2O$.Secondary $(2^o)$ amines react with $HNO_2$ to form $N$-nitrosamines,which are yellow oily liquids and do not evolve $N_2$ gas: $R_2NH + HNO_2 \rightarrow R_2N-N=O + H_2O$.Tertiary $(3^o)$ aliphatic amines form water-soluble nitrite salts with $HNO_2$ and do not evolve $N_2$ gas: $R_3N + HNO_2 \rightarrow [R_3NH]^+NO_2^-$.Therefore,both $2^o$ and $3^o$ amines do not evolve $N_2$ gas.

Which of the following amines does not evolve $N_2$ gas upon reaction with $HNO_2$?
