Bond order is an inverse measure of

Group the following molecules/ions according to their bond order: $O_2^{2-}, Li_2, O_2^{2+}, F_2, N_2, He_2^{2+}$.

The correct order of energies of molecular orbitals of $N_2$ molecule is

In dinitrogen tetroxide $(N_2O_4)$,there:

What is the bond order of the $O_2$ molecule?

Thermal decomposition of $AgNO_3$ produces two paramagnetic gases. The total number of electrons present in the antibonding molecular orbitals of the gas that has the higher number of unpaired electrons is. . . . .
