Which of the following molecules has the maximum number of A-X bonds of identical length, where ‘A” is the central atom and ‘X’ is the surrounding atom?
1 \({\rm{S}}{{\rm{F}}_{\rm{6}}}\)
2 \({\rm{I}}{{\rm{F}}_{\rm{7}}}\)
3 \({\rm{P}}{{\rm{F}}_{\rm{5}}}\)
4 \({\rm{ClO}}_{\rm{4}}^{\rm{ - }}\)
Explanation:
\({\rm{S}}{{\rm{F}}_{\rm{6}}}\) = Octahedral and all six S-F bond length are same.

Which of the following molecule has maximum number of \(90^{\circ}\) bond angles?
1 \(\mathrm{XeF}_{4}\)
2 \(\mathrm{XeF}_{5}^{-}\)
3 \(\mathrm{SF}_{6}\)
4 \(\mathrm{IF}_{7}\)
Explanation:
\(\mathrm{sp}^{3} \mathrm{~d}^{2}\) - no. l.p. on central atom - octahedral and all angles are \(90^{\circ}\). So maximum \(90^\circ \) angles are present in \({\rm{S}}{{\rm{F}}_6}.\)
