Answer
Saturated hydrocarbons: each carbon atom has the maximum number of hydrogens, the hydrocarbon has single covalent bonds (alkanes).
Unsaturated hydrocarbons: each carbon atom does not have the maximum number of hydrogens because of the presence of double (alkene) or triple covalent bonds (alkyne).
