What are alkenes?

Answer»

Alkenes are unsaturated hydrocarbons having at least one (C = C) double bond in their structures, Alkenes are also called olefins. Their general formula is CnH2n

Ex : Ethylene (C2 H4) and propene (C3 H6), etc.

•The common family of hydrocarbons found in crude oil is the alkenes. In this family there is at least one carbon–carbon double bond. This double bond makes a big difference to the chemistry of the compounds of the family.

•The general formula for alkenes can be written as CnH2n, where n=2,3,4....
