Definition of Hydrocarbons
The organic compounds which contain carbon and hydrogen only are termed as Hydrocarbon.
Classification of Hydrocarbons
Hydrocarbons are indefinitely large in numbers and they differ in structure, nature of bond and physical properties. Due to these hydrocarbons are divided into many classes .Similarly depending upon the nature of chain/ring structure hydrocarbons are classified as chain, branched and cyclic hydrocarbons. In cyclic hydrocarbons there is special category of benzene and benzene ring containing hydrocarbons called as aromatic hydrocarbons. Hence the classification of hydrocarbons can be explained here.
