During chemical bond formation the potential energy of the bonding atoms decreases. According to VBT bond strength depends on extent of over lapping. Shapes and bond angles of the molecules were explained by VSEPR theory. This theory explains the Geometry of the molecules based on the repulsions among the valance shell electron pairs. As number of lone pairs increases repulsions increases apd the shape is altered accordingly. Katio of lone pairs and bond pair electrons in H_(2) O molecule respectively

According to V.B.T. a covalent bond is formed by the overlapping of half filled atomic orbitals with electron spinning in the opposite direction. The strength of a bond depends on extent of overlapping. Double bond energy is not twice that of single bond energy because a double bond is made up of a weak a bond and strong o bond. According to V.B.T, in the formation of CH_4 molecule the type of overlappings observed are
