Question

An organic amino compound reacts with aqueous nitrous acid at low temperature to produce an oily nitroso amine. The compound is :

• A. $CH_{3}NH_{2}$
• B. $CH_{3}CH_{2}NH_{2}$
• C. $CH_{3}CH_{2}NH.CH_{2}CH_{3}$
• D. $(CH_{3}CH_{2})_{3}$

Answer 1

Answer: (C)

$CH_{3}CH_{2}NH.CH_{2}CH_{3}$

Answer 2

Secondary amines gives oily nitrosomine with nitrous acid.

$\mathbf{(C}\mathbf{H}_{\mathbf{3}}\mathbf{C}\mathbf{H}_{\mathbf{2}}\mathbf{)}_{\mathbf{2}}\mathbf{NH + HONO \rightarrow}$ $\underset{\text{oily}}{\mathbf{(C}\mathbf{H}_{\mathbf{3}}\mathbf{C}\mathbf{H}_{\mathbf{2}}\mathbf{)}_{\mathbf{2}}\mathbf{N.NO +}\mathbf{H}_{\mathbf{2}}\mathbf{O}}$
