Answer:
The property of self combination of carbon atoms to form long chains is called catenation.
Catenation
Catenation can be defined as the self-linking of atoms of an element to form chains and rings. Catenation occurs most readily in carbon, forming covalent bonds to form longer chains and structures with other carbon atoms. Carbon is best known for its catenation properties, with the analysis of catenate carbon structures in organic chemistry.
