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

    A)  \[C{{H}_{3}}N{{H}_{2}}\]             

    B) \[C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}\]

    C)   \[{{(C{{H}_{3}}C{{H}_{2}})}_{3}}N\]       

    D) \[{{(C{{H}_{3}}C{{H}_{2}})}_{2}}NH\]

    Correct Answer: D

    Solution :

    Sol.         Secondary amines give oily nitrosoamine with nitrous acid. \[\underset{{{2}^{o}}a\min e}{\mathop{{{(C{{H}_{3}}C{{H}_{2}})}_{2}}NH}}\,+HN{{O}_{2}}\xrightarrow{{}}\]                           \[\underset{oily\text{ }nitrosoamine}{\mathop{{{(C{{H}_{3}}C{{H}_{2}})}_{2}}N-NO}}\,+{{H}_{2}}O\]
