ethylene reacts with hcl faster than vinyl chloride. why
Answers
Answer:
vinyl chloride, also called chloroethylene, a colourless, flammable, toxic gas belonging to the family of organohalogen compounds and used principally in making polyvinyl chloride, or PVC, a widely used plastic with numerous applications.The major industrial preparation of vinyl chloride begins with ethylene and has two variants. In one, ethylene is converted to 1,2-dichloroethane (ethylene chloride) by reaction with chlorine. Heating 1,2-dichloroethane in the presence of a charcoal catalyst gives vinyl chloride.
In the other process (called oxychlorination), ethylene, hydrogen chloride, and oxygen (or air) are heated in the presence of a copper catalyst to give vinyl chloride and water.
Typically, a vinyl chloride plant is designed to integrate the two processes so that the hydrogen chloride produced by heating 1,2-dichloroethane is used as a reactant in the oxychlorination method.

Processes based on acetylene were developed in the 1930s and are more direct, but because acetylene is much more expensive than ethylene, these processes are used far less than ethylene-based ones.
Vinyl chloride can cause liver damage, and it is classified as a known human carcinogen.

Vinyl chloride is an organochloride with the formula H2C=CHCl that is also called vinyl chloride monomer (VCM) or chloroethene. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). About 13 billion kilograms are produced annually. VCM is among the top twenty largest petrochemicals (petroleum-derived chemicals) in world production.[2] The United States currently remains the largest VCM manufacturing region because of its low-production-cost position in chlorine and ethylene raw materials. China is also a large manufacturer and one of the largest consumers of VCM.[3] Vinyl chloride is a gas with a sweet odor. It is highly toxic, flammable, and carcinogenic. It can be formed in the environment when soil organisms break down chlorinated solvents. Vinyl chloride that is released by industries or formed by the breakdown of other chlorinated chemicals can enter the air and drinking water supplies. Vinyl chloride is a common contaminant found near landfills.[4] In the past VCM was used as a refrigerant.[5]
