Hydrocarbons are organic compounds which contain only carbons and hydrogen in their structure.
(a) Saturated Hydrocarbons:
They contain only single bonds between the carbon atoms. The valency of “C” is fully utilized
Examples: All Alkanes
(b) Unsaturated Hydrocarbons:
Unsaturated Hydrocarbons are those which contain one or more double or triple bonds. It means that the valency of carbons is not fully utilized. Examples: Alkenes and Alkynes
These are composed of open chains of Carbon atoms. They can be: (a) Saturated (b) Unsaturated
Saturated Hydrocarbons contain only single bonds between C atoms. e.g. Alkanes
Unsaturated Hydrocarbons contain one or more double or triple bonds. e.g. Alkenes Ethene
Alicyclic Hydrocarbons contain carbon atoms arranged in rings. They have two fewer hydrogen atoms than Alkanes.
Aromatic compounds are hydrocarbons which contain six-member ring (Benzene ring) into which there is three carbon. Carbon alternate double bonds. They have a specific smell.
