Question

Chemical formula of Westrosol is ______.

Options

• C₂H₂Cl₄

• C₂H₄

• C₂HCl₃

• None of the above

Answer 1

Chemical formula of Westrosol is C₂HCl₃.

Explanation:

Westrosol is the commercial name for trichloroethene (or trichloroethylene). The industry prepares it by heating Westron (C₂H₂Cl₄) with lime water, which causes dehydrochlorination (removal of an HCl molecule). The resulting compound contains a carbon-carbon double bond with three chlorine substituents, giving it the molecular formula C₂HCl₃ (chemically structured as \[\ce{CCl2 = CHCl}\].
