(Kimya) Catenation is the ability of a chemical element to form covalent bonds with itself, resulting in ring, chain and cage structures. The element most well known for its catenation is carbon, with organic chemistry being essentially the study of catenated carbon structures (otherwise known as catenae). However, carbon is by no means the only element capable of forming such catenae, and several other main group elements are capable of forming an expansive range of catenae
the property of a few elements, most especially carbon, to yield chains and rings by forming covalent bonds with atoms of the same element
Connection of links or union of parts, as in a chain; a regular or connected series
