General description
Ethylene is an alkene used in Friedel-Crafts alkylation, cycloaddition, electrophilic addition, and vinylation reactions.
Application
Ethylene is mainly used as a precursor to synthesize polyethylene, ethylbenzene and ethylene dichloride. It is also used in the preparation of single- layer graphene by thermal chemical vapor deposition.
