Q5 / 75 · JEE Main 2025 (4 Apr Shift 2) · Chemistry
Given below are two statements:
Statement (I) : for $\mathrm{ClF}_3$, 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 (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:
- AStatement I is incorrect but statement II is correct.
- Correct answerBStatement I is correct but statement II is incorrect.
- CBoth Statement I and statement II are correct.
- DBoth 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.
Statement 2 is incorrect since in $\mathrm{sp}^3 \mathrm{~d}$ hybridization; lone pair cannot occupy axial position.
Hence, the correct answer is option: 'B'.
