    Which will undergo reaction with ammoniacal \[AgN{{O}_{3}}\] [DPMT 1996]

    A) \[\begin{matrix}    C{{H}_{3}}  \\    C{{H}_{3}}  \\ \end{matrix}>CH-C{{H}_{2}}-CH=CH-C{{H}_{3}}\]

    B) \[C{{H}_{3}}-CH=CH-C\equiv CH\]

    C) \[C{{H}_{3}}-C{{H}_{2}}-CH=CH-C{{H}_{2}}-C{{H}_{3}}\]

    D) \[C{{H}_{2}}=CH-C{{H}_{2}}-C{{H}_{3}}\]

    E) None

    Correct Answer: B

    Solution :

           \[C{{H}_{3}}-CH=CH-C\equiv C-H\]. Acidic hydrogen  (H atom attached to triple bond) is present therefore it gives reaction with ammoniacal \[AgN{{O}_{3}}\].
