Vedclass · Answer

(A) Secondary amines (containing $NH$ group) when treated with $HNO_{2}$ give $N-$nitrosoamines which separate as yellow oily liquids.The structures of the given compounds are:$(A)$ Ethyl methyl amine: $CH_{3}-NH-C_{2}H_{5}$ $(2^{\circ})$$(B)$ Aniline: $C_{6}H_{5}NH_{2}$ $(1^{\circ})$$(C)$ $3-$methyl benzyl amine: $CH_{3}-C_{6}H_{4}-CH_{2}NH_{2}$ $(1^{\circ})$$(D)$ Methyl amine: $CH_{3}NH_{2}$ $(1^{\circ})$Among the given compounds,only ethyl methyl amine is a secondary amine,thus it gives a yellow oily liquid with $HNO_{2}$.

Which of the following amines gives a yellow oily liquid with $HNO_{2}$?
