Which of the following statements is not applicable to carbon compounds?

The correct option is B

They are ionic in nature.

Carbon has the ability to form covalent bonds with other atoms of carbon giving rise to a large number of molecules through a self-linking property. This property is called catenation. Since the valency of carbon is four, it is capable of bonding with four other atoms. As carbon forms covalent bond with other elements, so the compounds formed are also covalent in nature. Carbon compounds have low melting and boiling points because of their covalent nature.
