carbocyclic compound

A carbocyclic compound is an organic chemical compound where the ring structure is composed solely of carbon atoms. These compounds are also referred to as alicyclic compounds if they contain three or more carbon atoms linked in a ring. The carbon atoms in these rings can be connected by single, double, or triple bonds.12

For example, cyclopentane (C₅H₁₀) is a carbocyclic compound where five carbon atoms form a ring, with hydrogen atoms attached to each carbon. In contrast, heterocyclic compounds are similar but contain at least one atom of an element other than carbon within their ring structure. These heteroatoms, such as nitrogen or oxygen, give heterocyclic compounds distinct properties compared to their all-carbon ring counterparts.34
