- AThe spin magnetic moment of $KO_2$ is $1.73\,BM$
- BThe hybridisation of $B$ in $H_3BO_3$ is $sp^2$
- CIn $H_2S_2O_8\, S-S$ linkage is present
- ✓In $ClF_3$ axial and Equatorial bonds are not identical
The valence shell electron configuration of first excited state of sulphur is $3 \mathrm{s}^{2} 3 \mathrm{p}^{3} 3 \mathrm{d}^{1}$
The valence shell electron configuration of second excited state of sulphur is $3 \mathrm{s}^{1} 3 \mathrm{p}^{2} 3 \mathrm{d}^{2}$.
This is followed by sp ${ }^{3} \mathrm{d}^{2}$ hybridization to form $\mathrm{SF}_{6}$.
Thus $\mathrm{SF}_{6}$ is formed in the second excitation state of sulphur atom.
