Carbon forms bonds not only with hydrogen but also with halogens, oxygen, nitrogen, and sulphur. These elements can replace hydrogen in a hydrocarbon chain, maintaining carbon’s valency.

Carbon’s unparalleled catenation is attributed to its capacity to form strong bonds with other carbon atoms. With a valency of four, carbon can bond with multiple atoms, producing stable compounds with diverse elements due to the strength of its bonds.

Carbon compounds with only single bonds between carbon atoms are termed saturated, while those with double or triple bonds are referred to as unsaturated. The nature of bonding influences the properties of these compounds.

Carbon’s ability to form bonds with other carbon atoms, known as catenation, enables the formation of long chains, branched structures, or rings in carbon compounds. This property contributes to the vast diversity of carbon compounds.

Covalently bonded molecules have strong intramolecular bonds but weak intermolecular forces, resulting in low melting and boiling points. Since no charged particles are formed, these compounds are generally poor conductors of electricity.
