Carbon forms a large number of compounds because of the following reasons:

(a) Tetravalency: Carbon atoms readily form covalent bonds with the other atoms.

(b) Catenation: Two carbon atoms readily form covalent bonds and this bond is more stable than the bonds formed by the other elements.

(d) The electronegativity of the carbon atom is average.

a. Saturated hydrocarbons produce clean flame while unsaturated carbon compounds produce yellow flame with black smoke. The burning of carbon compounds results in a sooty deposit on the surface or a sooty flame if there is an incomplete combustion of saturated hydrocarbons due to limited supply of air.
