Give three reasons for the existence of a large number of carbon compounds?
Catenation: The unique property of the 'C' element to be able to form continuous links with other 'C' atoms through covalency called catenation is one reason for the existence of a large number of organic compounds.
Formation of Multiple Bonds: Two 'C' atoms can either be linked through a single bond or a double bond
This leads to the formation of a variety of organic compounds.
Isomerism: This property, shown by organic compounds, which have same molecular formula but different structural formula, is also a reason for the formation of a large number of organic compounds. Example: For C4H10 formula there could be two isomers.
