Carbon atom has four valence electrons.

Carbon can gain four electrons and form C^4- anion or lose four electrons to form the C⁴⁺ cation.

It forms four covalent bonds by sharing its valence electrons with other atoms.

This is known as tetravalency of carbon.

Due to its smaller size, electronic configuration and maximum bond energy that is greater strength of bonds,

carbon has tendency to form multiple bonds.

Due to small size, carbon has strong tendency to form multiple bond with other

carbon atoms,oxygen atoms or nitrogen atoms.
