Question

what is catenation ​

Answer 1

Catenation is the bonding of atoms of the same element into a series, called a chain. A chain or a ring shape may be open if its ends are not bonded to each other, or closed if they are bonded in a ring.

The best example for catenation would be the formation of carbon chains and rings.

Answer 2

In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. ... Catenation occurs most readily with carbon, which forms covalent bonds with other carbon atoms to form longer chains and structures. This is the reason for the presence of the vast number of organic compounds in nature.
