Calomel (Hg_2 Cl_2) on reaction with ammonium hydroxide gives

Calomel (Hg2Cl2)\left(\mathrm{Hg}_2 \mathrm{Cl}_2\right) on reaction with ammonium hydroxide gives

Options

  1. AHgNH2Cl\mathrm{HgNH}_2 \mathrm{Cl}
  2. BNH2−Hg−Hg−Cl\mathrm{NH}_2-\mathrm{Hg}-\mathrm{Hg}-\mathrm{Cl}
  3. CHg2O\mathrm{Hg}_2 \mathrm{O}
  4. DHgO\mathrm{HgO}

Correct answer

A. HgNH2Cl\mathrm{HgNH}_2 \mathrm{Cl}

Step-by-step solution

HgCl+2NHOH⟶Hg+Hg(NH2)Cl+NH4Cl+2H2O\mathrm{Hg} \mathrm{Cl}+2 \mathrm{NHOH} \longrightarrow \mathrm{Hg}+\mathrm{Hg}\left(\mathrm{NH}_2\right) \mathrm{Cl}+\mathrm{NH}_4 \mathrm{Cl}+2 \mathrm{H}_2 \mathrm{O}
