Question

what is catenation? and give examples​

Answer 1

The property of element due to which it forms covalent bonds with other atoms of the same element to form a chain of atoms is called catenation.

Carbon has a unique nature in that it is able to catenate and form millions of organic compounds. Carbon shows the property of catenation to the maximum extent. Apart from carbon sulphur, silicon etc also show this property to some extent.


Examples are sulphur show catenation up to eight atoms in the formation of S8 molecules of sulphur. It also shows catenation in polysulphide ions Sn2-, Sulphanes H-Sn-H and polysulfuric acid HO2S-Sn-SO3H.

Answer 2

The property of direct bonding between atoms of same elements to form a chain.

The carbon chains can be straight or branched forming large molecules.

example carbon is the most common element that exhibit catenation .it can form long hydrocarbon chains and ring like benzene.
