Given below are two statements: Statement (I) : for ${\underset{\bullet \bullet}{\bullet \bullet}}_{\bullet \bullet}^{\bullet} \mathrm{F}_3$, all three possible structures may be drawn as follows. Statement (II) : Structure III is most stable, as the orbitals having the lone pairs are axial, where the $\ell \mathrm{p}-\mathrm{bp}$ repulsion is minimum. In the light of the above statements, choose the most appropriate answer from the options given below:
Statement I is incorrect but statement II is correct.
Statement I is correct but statement II is incorrect.
Both Statement I and statement II are correct.
Both Statement I and statement II are incorrect.
Solution
Statement 1 is correct. Statement 2 is incorrect since in $\mathrm{sp}^3 \mathrm{~d}$ hybridization; lone pair cannot occupy axial position.
