It is the property of carbon or any other element by which the large number of atoms can be linked to form a long chain. Carbon has the maximum catenation property. Carbon itself combines with other carbons to form a long chain. This combination may give cyclic or acyclic structure.
The carbon-carbon bond enthalpy is about 347.0 KJ– which is very high. High bond enthalpy is the main cause for very effective catenation property in carbon. Strong covalent bond between the carbon atoms favors the catenation property in carbon.
Carbide: Compounds of carbon with metals is called carbides.
