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 bond energy The expected bond angle in NH_3 molecule according to V.B.T is
