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

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

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

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

    Correct Answer: C

    Solution :

               Secondary amines gives oily nitrosamine with nitrous acid.                                 \[{{(C{{H}_{3}}C{{H}_{2}})}_{2}}NH+HONO\to \]\[\underset{\text{oily}\,\,\,\,\,\,\,\,\,\,\,}{\mathop{{{(C{{H}_{3}}C{{H}_{2}})}_{2}}N.NO+{{H}_{2}}O}}\,\]
