Alkene: An alkene is a hydrocarbon with at least one carbon-carbon double bond. Ethene (C2H4) is an example of an alkene.
Polymerization: Polymerization refers to the process in which small molecular units called monomers join together chemically to form large repeating chains or networks called polymers. Ethene can be polymerized to produce polyethylene, a common plastic material.
Double Bond:A double bond is a type of chemical bond formed when two pairs of electrons are shared between two atoms. Ethene contains a carbon-carbon double bond.
