Almost all compounds of carbon form covalent bonds. Give reason.

Answer»

Carbon (Z = 6) have electronic configuration of 1s2 2s2 2p2 . It is not possible for the carbon to form either C4+ or C4- ions to attain the nearest noble gas configuration as it requires large amount of energy. This implies that carbon cannot form ionic bond. So almost in all compounds of carbon, it form four covalent bonds.
