Question

Explain the following :
1. Tetravalency
2. catenation

Answer 1

Answer:

1) A carbon atom completes its octet only by sharing its valence electrons with other atoms. As a result, a carbon atom forms four covalent bonds by sharing valence electrons with other atoms. This is known as tetravalency of carbon ("tetra" means four)

2)Catenation can be defined as the self-linking of atoms of an element to form chains and rings.

Answer 2

Answer:

1.tetravalency-Carbon has a valency of four, so it is capable of bonding with four other atoms of carbon or atoms of some other monovalent element. This is known as tetravalency of carbon.

2.catenation-Catenation is the binding of an element to itself through covalent bonds to form chain or ring molecules. Examples: Carbon is the most common element that exhibits catenation. It can form long hydrocarbon chains and rings like benzene.
