Alkanes are classified as saturated hydrocarbons because they have a single bond that joins the carbon chains of atoms. Both Alkenes and alkynes are unsaturated hydrocarbons, which means they have two or more bonds. Alkenes have double bonds, while the alkyne has triple bonds. .the general formula of Alkanes is CnH2n+2, while the general formula of alkenes is CnH2n, and the general formula of alkynes is CnH2n-2.

The single carbon alkane is called Methane, while the single carbon form of alkene and alkyne do not exist in nature. Alkanes are very stable hydrocarbons as the carbon to carbon bonds cannot be easily broken. This is because of the saturation, due to this, they cannot undergo addition reaction, and they can only undergo substitution reaction.

Alkenes are more stable than alkynes and less stable than Alkanes. Both Alkenes and alkynes have lower stability due to the instauration; they both can undergo addition reaction.
