Question

The property of self – linkage of carbon atoms is called:
A.Polymerisation
B.Catenation
C.Cracking
D.neutralisation

Answer 1

Hint: Carbon is a versatile atom and possesses the capability of bonding with different atoms and molecules. Similarly, it can also bond with itself.

Complete step by step answer:
-In order to understand the answer for the given question, let us first understand the meanings of the different terms mentioned in the options.
-Polymerisation is a process by which we can connect a large number of monomeric molecules with each other in the form of a chain or mesh network. The macromolecules formed during polymerization often have a linear or branched structure. But there are certain situations in which it assumes the shape of a complex three – dimensional network. -The linkage in polymers takes place between different types of atoms and not just C – C linkage.
-Catenation literally means self – binding or self-linkage of an element with itself through covalent bonds to form chain or ring molecules.
-Cracking is the opposite of binding. In cracking, a large saturated hydrocarbon molecule are broken into smaller unsaturated hydrocarbons.
-Neutralisation is just a type of reaction in which an acid reacts with base in equivalent quantities and concentrations to cancel out the pH or pOH characteristics of each other to form a neutral salt and water.
-Hence, the property of self – linkage of carbon atoms is called catenation.

Hence, Option B is the correct option.

Note:
Catenation, chemical linkage into chains of atoms of the same element, occurring only among the atoms of an element that has a valence of at least two and that forms relatively strong bonds with itself.
