Question

Explain formation of CH4 molecule on hybridisation

Answer 1

The bonds in a methane (CH4)molecule are formed by four separate but equivalent orbitals; a single 2s and three 2p orbitals of the carbon hybridize into four sp3 orbitals. ... In a water molecule, two sp3 hybrid orbitals are occupied by the two lone pairs on the oxygen atom, while the other two bond with hydrogen.

Answer 2

Answer:

1. The bonds in a methane (CH4) molecule are formed by four separate, but equivalent orbitals; a single 2s and three 2p orbitals of carbon hybridize into four sp3 orbitals.
2. The carbon atom in the ground state takes up energy and goes into excited state, which has four half-filled orbitals.
3. One orbital of 2s and three orbitals of 2p mix up forming four hybrid orbitals of equivalent energy. These are called sp3 hybrid orbitals.
4. The angle between them is 109.5°.

I hope you understand the answer!
