Question

How to learn molecules shape according to hybridization?

Answer 1

Valence bond theory helps us determine how many bonds there are between two atoms in a molecule

Orbital Hybridization Theory

In order to figure out the hybridization, we need to know the valence electrons in the participating atoms and the valance bond theory. The valence bond theory essentially says that all bonds are made by an atom donating a valence electron to another atom to complete its octet. The theory, combined with knowledge of valence electrons, tells us how many bonds there are between two atoms in a molecule. The VSEPR theory, as you've learned previously, helps predict the shape of a molecule based on the repulsion of the electrons in the orbitals. The VSEPR theory fails to explain all of the interactions scientists see in molecules, though. So they've developed the concept of orbital hybridization.
