What is $LCAO$? Explain.

Stability of the species $Li_2$, $Li_2^-$, and $Li_2^+$ increases in the order of:

Which molecule has the highest bond order?

Which among the following orbitals form $\delta$ molecular orbitals?

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. . . . .
