    Formaldehyde reacts with ammonia to give urotropine. The formula of urotropine is      [MP PMT 1989, 96, 2003; AIIMS 1982; NCERT 1987; MP PET 1990, 91, 2000; CPMT 1978, 82, 86, 97; KCET 2003]

    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 :

                    \[6HCHO+4N{{H}_{3}}\to \underset{\text{Urotropine}}{\mathop{{{(C{{H}_{2}})}_{6}}{{N}_{4}}}}\,+6{{H}_{2}}O\]
