This problem has been solved! The bond energies of all four compounds have been broken down into electrostatic, Pauli (exchange) and orbital terms at the equilibrium internuclear separation and as a function of r(X–X) using the Ziegler–Rauk energy decomposition scheme.

The bond length of the covalent bond is the nuclear seperation distance where the molecule is most stable.Or in simple words, bond length is the distance between the nuclei in a bond .The H-H bond length in moleular hydrogen is 74 pm.At this distance,attractive interactions are maximied relative to repulsive interreactions..

See the answer. The weakness of the F2 bond is therefore a combination of quantum mechanical (Pauli) and classical (electrostatic) factors. The small electrostatic term is itself a result of the F–F bond being c. 0.1 Å longer than might be expected, due to the large gradient in the Pauli repulsion around the equilibrium internuclear separation. The comparative weakness of the F2 bond is traced to the electrostatic energy, which is considerably smaller than would be expected on extrapolation of the trend in the I2 → Cl2 data. Join now.
