Explain the term with example : Unsaturated hydrocarbon

Explanation

i. Hydrocarbons having at least one carbon-carbon double or triple bond are called unsaturated hydrocarbons.
ii. The unsaturated hydrocarbons containing a carbon-carbon double bond are called alkenes.
iii. The unsatureated hydrocarbons containing a T carbon-carbon triple bond are called alkynes.
E.g. Ethene `(CH_(2)=CH_(2))` is an alkene while ethyne `(CH-=CH)`is an alkyne.
[Note : The unsaturated hydrocarbons are generally more reactive than saturated hydrocarbons.]
