Answer» Solution :Physical nature of carbon and its compounds. Carbon has the ability to form covalent BONDS with other atoms of carbon giving rise to a large number of molecules through self linking property which is called catenation. Carbon combines with oxygen, hydrogen, nitrogen SULPHUR, chlorine and many other elements to form various STABLE compounds. The stability of carbon compounds is due to the small size of carbon which enables the nucleus to hold on to the shared pair of electrons strongly. Carbon compounds show ISOMERISM, the PHENOMENON by which two or more compounds have same molecular formula but different structural formula with difference in properties. Carbon compounds have low boiling and low melting points because of their covalent nature. Carbon compounds are easily combustible.
