Question

discuss briefly the isomerism in alkene​

Answer 1

Alkenes are hydrocarbons which contain carbon-carbon double bonds. Their general formula is CnH2n for molecules with one double bond (and no rings). This lack of free rotation also gives rise to geometric isomerism in alkenes (see 2-butene below for an example).
