Explain the term with example : Hetero atom in a carbon compound

Explanation

Carbon compounds are formed by formation of bonds of carbon with other elements such as halogens, oxygen, nitrogen , sulphur. The atoms of these elements substitute one or more hydrogen atoms in the hydrocarbon chain and thereby the tetravalency of carbon atoms in the hydrocarbon chain and thereby the tetravalency of carbon is satisfied. The atom of the element which is substitute for hydrogen is referred to as a hetero atom. Sometimes hetero atoms are not alone but exist in the form of certain groups of atoms.
