Alkenes are unsaturated hydrocarbons which mean they are compounds with one or more double bonds between carbon atoms.
The general formula of alkene is-CnH2n
Alkynes:
Alkynes are unsaturated hydrocarbons which mean they are compounds with one or more triple bonds between carbon atoms.
The general formula of alkene is-CnH2n−2
