Question

Westrosol is:
A.$\text{C}{{\text{l}}_{\text{2}}}\text{C = CHCl}$
B.$\text{CHC}{{\text{l}}_{\text{2}}}\text{-CHC}{{\text{l}}_{\text{2}}}$
C.$\text{C}{{\text{H}}_{\text{2}}}\text{Cl-C}{{\text{H}}_{\text{2}}}\text{Cl}$
D.$\text{C}{{\text{H}}_{\text{3}}}\text{-CC}{{\text{l}}_{\text{3}}}$

Answer 1

Westrosol is a chemical compound that is used as an industrial solvent. The chemical name of westrosol is Trichloroethylene. It is a clear, odourless liquid that is non-flammable in nature.

Complete answer:
The chemical compound trichloroethylene has industrial abbreviations such as TCE, Trichlor, Tri, Tricky, and Trike. It has a sweet smell like that of chloroform. It is old under a number of trade names such as Trimar and Trilene. Trichloroethylene was used as a volatile anaesthetic and as an inhaled obstetrical analgesic in a number of patients. The chemical formula of Westrosol is$\text{C}{{\text{l}}_{\text{2}}}\text{C = CHCl}$. Groundwater and drinking water contamination from the industrial discharges is a major concern for human health.

Hence, the correct option is option A.
Note:
The production of Westrosol starts with acetylene and is treated with chlorine using a ferric chloride catalyst at 90$^{\text{0}}\text{C}$ to produce 1,1,2,2-tetrachloroethylene. This product is then dechlorinated by calcium hydroxide to form trichloroethylene. Nowadays however most of the trichloroethylene is chlorinated over ferric chloride catalyst to form 1,2-dichloroethylene which when heated at around 400$^{\text{0}}\text{C}$ forms trichloroethylene or Westrosol. The reaction is catalysed by a variety of substances; the most commonly used one is a mixture of potassium chloride and aluminium chloride. Different forms of porous carbon can also be used. This reaction can produce tetrachloroethylene as a by-product depending on the number of chlorine atoms fed to the reactants during the reaction. Trichloroethylene is used as a solvent in a number of processes for a variety of organic materials.
