The Lewis structure of vinyl chloride reveals a carbon-carbon double bond with two hydrogen atoms attached to one carbon and a chlorine atom bonded to the other. The arrangement of atoms follows a tetrahedral geometry, with the carbon-carbon double bond lying in one plane and the hydrogen and chlorine atoms positioned in the perpendicular plane. This structure forms due to the sp² hybridization of the carbon atoms, resulting in trigonal planar geometry and the formation of sigma bonds in the molecular plane.
