Question

Hybridization of H2O​

Answer 1

Explanation:

To do hybridization of H2O, we look for the central atom in the molecule. The central atom is Oxygen so we do hybridization with respect to oxygen. Oxygen contains 2 lone pairs of electrons + 2 sigma bonds with Hydrogen atom therefore it occupies 4 orbitals.

Answer 2

H2O has $s{p}^{3}$ hybridisation

Knowledge cell:

• Definition of hybridisation: Mixing of different shapes and approximate equal energy atomic orbitals and redistribution of energy to form new orbitals of same shape and energy is called hybridisation.

• The new orbitals formed by hybridisation are called hybrid orbitals.

• In sp3 hybridisation, one s orbital and three p orbital are mixed to give four new hybrid orbitals.

• H2O molecule has two sigma bonds and two lone pair of electrons.

• Due to the presence of lone pair, the bond angle is either less than 109°28' or more than 109°28'

• In H2O the hybridisation on Oxygen atom is sp3 but due to presence of lone pair electrons they repel each other.

• Their molecular geometry is Angular.
