Question

explain the tetravalency of carbon atom?

Answer 1

tetravalency is a property of carbon atom which allows it to make bonds with 4 other carbon atoms or any other element

Answer 2

A carbon atom has four electrons in its outermost valence shell. So, it needs four more electrons to complete its octet. A carbon atom completes its octet only by sharing its valence electrons with other atoms. As a result, carbon atom forms four covalent bonds by sharing valence electrons with other atoms. This is known as tetravalency of carbon.
