    Calomel \[(H{{g}_{2}}C{{l}_{2}})\] on reaction with ammonium hydroxide gives

    A) \[HgO\]

    B) \[H{{g}_{2}}O\]

    C) \[N{{H}_{2}}-Hg-Hg-Cl\]

    D) \[HgN{{H}_{2}}Cl\]

    Correct Answer: D

    Solution :

    \[H{{g}_{2}}C{{l}_{2}}+2N{{H}_{3}}\xrightarrow{{}}\underset{white}{\mathop{HgN{{H}_{2}}Cl}}\,+\underset{black}{\mathop{Hg}}\,+N{{H}_{4}}Cl\]
