Question

What is the product obtained in the reaction of $HgC{{l}_{2}}$ and$Hg{{(CN)}_{2}}$?
(A) ${{(CN)}_{2}}$
(B) Addition compound $HgC{{l}_{2}}.Hg{{(CN)}_{2}}$
(C) $Hg(CN)Cl$
(D) $Hg{{[Hg(CN)]}_{2}}C{{l}_{2}}$

Answer 1

Hint: Mercuric cyanide, also referred to as mercury (II) cyanide, is a chemical compound made of mercury. It is a poisonous, white powder with no smell. In polar solvents like water, alcohol, and ammonia, it is highly soluble; in ether, it is just mildly soluble; and in benzene and other hydrophobic solvents, it is insoluble. The inorganic chemical compound of mercury and chlorine is mercury (II) chloride ($HgC{{l}_{2}}$). It is a chemical molecule that is extremely hazardous to humans and is a white crystalline solid used as a scientific reagent.

Complete step by step solution:
$HgCL_2+Hg(CN)_2\rightarrow HgCL_2.Hg(CN)_2$
The product obtained in the reaction of $HgC{{l}_{2}}$ and $Hg{{(CN)}_{2}}$is an addition compound$HgC{{l}_{2}}.Hg{{(CN)}_{2}}$.$HgC{{l}_{2}}$ has many uses. It can be used in leather tanning, dry battery cases, as an ant repellent, in the manufacturing of ink for mercurography, etc.

It can also be used as a catalyst in the conversion of acetylene to vinyl chloride. $Hg{{(CN)}_{2}}$ is employed in the production of cyanogen gas, photography, and germicidal soaps.
Correct Option: (B) Addition compound $HgC{{l}_{2}}.Hg{{(CN)}_{2}}$

Note: The chemical molecule known as cyanogens has the formula ${{(CN)}_{2}}$. It is a flavourless, extremely poisonous gas with a strong odour. It is a pseudo halogen molecule. Cyanogen molecules have two $CN$ groups and are similar to diatomic halogen compounds in this respect. It is a linear molecule. Long-term contact with fire or extreme heat can cause ${{(CN)}_{2}}$ containers to explode violently and discharge into the air.
