Molecular orbital theory was developed mainly by
Select the $CORRECT$ statement if internuclear axis is $y-$ axis
Match each of the diatomic molecules in Column $I$ with its property / properties in Column $II$.
Column $I$ | Column $II$ |
$(A)$ $\mathrm{B}_2$ | $(p)$ Paramagnetic |
$(B)$ $\mathrm{N}_2$ | $(q)$ Undergoes oxidation |
$(C)$ $\mathrm{O}_2^{-}$ | $(r)$ Undergoes reduction |
$(D)$ $\mathrm{O}_2$ | $(s)$ Bond order $\geq 2$ |
$(t)$ Mixing of ' $\mathrm{s}$ ' and ' $\mathrm{p}$ ' orbitals |
