Remedy: Hybridisation: It is described as the whole process of intermixing of atomic oribitals of a bit unique energies to provide increase to new hybridized orbitals having equal Strength and similar shapes.
as the addition of one or more electrons would lead to amplified repulsion Among the many electrons as well as a decrease in effective nuclear charge.
Because of two lone pairs of electrons on O-atom, repulsion on bond pairs is bigger in H20 in comparison to NH3 . Hence, the bond angle is significantly less in H20 molecules.
