    Urotropine is obtained by the reaction of\[N{{H}_{3}}\]with

    A)  \[C{{H}_{3}}OH\]       

    B)  \[HCHO\]

    C)  \[C{{H}_{3}}CHO\]      

    D)  \[C{{H}_{3}}COC{{H}_{3}}\]

    Correct Answer: B

    Solution :

     Formaldehyde (HCHO) reacts with ammonia to form   hexamethylene   tetramine,\[{{(C{{H}_{2}})}_{6}}{{N}_{4}}\]which is known as urotrppine. \[\underset{formaldehyde}{\mathop{6HCHO}}\,+4N{{H}_{3}}\xrightarrow[{}]{{}}\underset{urotropine}{\mathop{{{(C{{H}_{2}})}_{6}}{{N}_{4}}}}\,+6{{H}_{2}}O\] Urotropine is used as a medicine to treat urinary infections.
