The term hydrocarbon means compounds of hydrogen and carbon only.
Classification of organic compounds
Depending upon the type of carbon-carbon bond present hydrocarbons can be classified as:
- Saturated hydrocarbon
- Unsaturated hydrocarbons
- Aromatic hydrocarbons
Alkane is a saturated hydrocarbon in which carbon is attached to C-C single bond.
Alkene is a unsaturated hydrocarbon in which carbon is attached to carbon carbon double bond.
Alkyne is a unsaturated hydrocarbon in which carbon is attached to carbon carbon triple bond.
In Aromatic hydrocarbon there is one or more benzene ring present.
