    A) \[{{(C{{H}_{2}})}_{6}}{{N}_{4}}\]              

    B) \[{{(C{{H}_{2}})}_{4}}{{N}_{3}}\]

    C) \[{{(C{{H}_{2}})}_{6}}{{N}_{6}}\]              

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

    Correct Answer: A

    Solution :

    Formaldehyde reacts with ammonia to give urotropine. The formula of urotropine is\[{{(C{{H}_{2}})}_{6}}{{N}_{4}}\] \[6HCHO+4N{{H}_{3}}\xrightarrow{{}}\underset{\begin{smallmatrix}  urotropine \\  (hexamethylene\,  \\  tetramine) \end{smallmatrix}}{\mathop{{{(C{{H}_{2}})}_{6}}{{N}_{4}}}}\,+6{{H}_{2}}O\]
