    Identify the product (P) in the following reaction series, \[C{{H}_{3}}CN\xrightarrow[{}]{Na/{{C}_{2}}{{H}_{5}}OH}(X)\xrightarrow[{}]{HN{{O}_{2}}}(Y)\xrightarrow[C{{H}_{2}}C{{l}_{2}}]{PCC}(Z)\xrightarrow[(ii){{H}_{3}}{{O}^{+}}]{(i)Ag(N{{H}_{3}})_{2}^{+}}(P)\]

    A)  \[C{{H}_{3}}CHO\]                       

    B)  \[C{{H}_{3}}CON{{H}_{2}}\]

    C)  \[C{{H}_{3}}COOH\]                    

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

    Correct Answer: C

    Solution :

     \[C{{H}_{3}}CN\,\xrightarrow{Na/{{C}_{2}}{{H}_{5}}OH}\,C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}\xrightarrow{HN{{O}_{2}}}\]\[C{{H}_{3}}C{{H}_{2}}OH\xrightarrow{[O]}\,C{{H}_{3}}CHO\,\xrightarrow[reagent]{Tollen's}\]\[C{{H}_{3}}COOH\]
