Saturated hydrocarbons Unsaturated hydrocarbons

Saturated hydrocarbons	Unsaturated hydrocarbons
i.              In saturated hydrocarbons, the carbon atoms are linked to each other only by a single covalent bonds. ii.            They contain only single bond. iii.           These compounds are chemically less reactive. iv.           Substitution reaction is a characteristic property of these hydrocarbons. v.             Their general formula is CnH2n+2.	i.              In unsaturated hydrocarbons, the valencies of carbon atoms are not fully satisfied by single covalent bonds. ii.            They contain carbon to carbon double or triple bonds. iii.           These compounds are chemically more reactive. iv.           Addition reaction is a characteristic property of these hydrocarbons. v.             Their general formula is CnH2n  or CnH2n - 2.
