Question

tetravalency in carbon?
plz write understandable answer.

Answer 1

hello dear....
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).

Answer 2

Hey !

Tetravalency of Carbon:

Electronic Configuration of Carbon: 2, 4

This is because, carbon has 6 electrons in total. 2 electrons from Carbon gets transformed to the First 'K' Shell and the remaining move on to the 'L' shell.

So Carbon has 4 electrons in the last or valence shell. These 4 electrons can share with other elements having less electrons in the valence shell.

Since 4 electrons are available for bonding, it is called tetravalency as tetra represents 4.
