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.
