Unsaturated HydrocarbonsHydrocarbons that don’t contain all single
bonds between the carbon atoms.
Alkanes are saturated hydrocarbons.They only contain single bonds.
AlkenesHave the general formula CnH2n
Structure contains at least one double bond.When naming them, the parent chain name ends in –ene.
