Hybridization was introduced to explain molecular structure when the valence bond theory failed to correctly predict them. It is experimentally observed that bond angles in organic compounds are close to 109°, 120°, or 180°. According to Valence Shell Electron Pair Repulsion (VSEPR) theory, electron pairs repel each other and the bonds and lone pairs around a central atom are generally separated by the largest possible angles.

According to VSEPR theory , bond angles in organic compounds are generally close to 109°, 120° or 180°.

Hybridization is defined as the mixing of two atomic orbitals which give rise to a new hybridized molecular orbital.

The hybrid orbitals so formed are different in energies and shapes. Equal energy atomic orbitals take part in hybridization. Since, valence bond theory failed to correctly predict the molecular structure, hybridization helps to understand the concept of bond formation, bond energies and bond lengths.

The shape of a molecule can be predicted from the electron pairs that surround the central atom by using Valence Shell Electron Pair repulsion (VSEPR) theory. This theory is based on the assumption that for a molecule to take a shape, its electronic repulsion should be minimized. That is why, according to experimental findings the angles between atoms of organic compounds are generally close to 109°, 120° or 180°.
