Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The species which have ${\mathrm{sp}}^2$ hybridisation with no lone pairs, ${\mathrm{sp}}^3{\mathrm{d}}^2$ hybridisation with two lone pairs are planar molecules.

The number of hybrid orbitals can be calculated as follows,

No.of hybrid orbitals = 1/2(V+M-C+A)

V = number of valence electrons

M = number of monovalent atoms attached to central atom.

C = Number of positive charges on the molecule

A = Number of negative charges on the molecule
