According to molecular orbital theory molecules are said to be stable if the number of electrons in bonding molecular orbitals is …………… the number of electrons in antibonding molecular orbitals.

L.C.A.O. Principle is involved in the formationof the molecular orbitals according ot molecular orbital theory. The energy of the bonding molecular orbital is less than that of thecombining atomic orbitals while that of the antibonding molecular orbitals while that of the order (B.O.)=1/2(N_(b)-N_(a)) helps in predicting (i) formation of molecules/molecular ions, bond dossociation energy, stability and bond length. Only the molecules or ions with positive B.O. can be formed. These will be diamagnetic if all molecular orbitals are dilled and paramagnetic if one of more are half filled. The atomic prbitals at the time of overlap must have the same symmetry as well. The bond order (B.O.) in B_(2) molecule is:

A bonding molecular orbital has lesser energy than the corresponding antibonding molecular orbital. Justify

Assertion(A) - Fluorine molecule has bond order one. Reason(R)-The number of electrons in antibonding molecular orbital is two less than that of bonding molecular orbitals.

Molecular orbitals are formed by the overlap of atomic orbitals. The combining orbitals must have proper orientation so that they can overlap to a considerable extent. Two atomic orbitals combine to form two molecular orbitals called bonding molecular orbital and antibonding molecular orbital. Bonding molecular orbital is stable and antibonding molecular orbital is unstable. sigma MO is formed by head on overlap while pi MO is formed by sidewise overlap. The MOs are filled with electrons according to the same rules as followed for filling atomic orbitats. Bond order is one of the most important parameter to compare the bond strength and bond length of bonds. Why has N_2 a larger dissociation energy than N_2 ^(+) whereas O_2 has a lower dissociation energy than O_(2)^(+) ?
