Explain energy level diagram for molecular orbital form by $1\mathrm{s}$ orbitals.
In which of the following process, the value of bond order & magnetic nature does not change?
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 |
The correct order of the $O-O$ bond length in $O_2$ , $H_2O_2$ and $O_3$ is
