    In the reaction,\[HC\equiv CH+2AgN{{O}_{3}}\xrightarrow{N{{H}_{4}}OH}\]                \[X+2N{{H}_{4}}N{{O}_{3}}+2{{H}_{2}}O\] X is

    A)  \[A{{g}_{2}}C\]                                

    B)  \[A{{g}_{2}}{{C}_{2}}\]

    C)  AgC                      

    D)  AgOH

    Correct Answer: B

    Solution :

                    \[HC\equiv CH+2AgN{{O}_{3}}\xrightarrow{N{{H}_{4}}OH}\]\[AgC\equiv CAg\] or \[(A{{g}_{2}}{{C}_{2}})+2N{{H}_{4}}N{{O}_{3}}+2{{H}_{2}}O\]  white precipitate (X)
