Which of the following shapes of SF4 is more stable and why?

Question

Which of the following shapes of SF4 is more stable and why? (A) (i), due to 3 lp-bp repulsions at 90° (B) (ii), due to 2 lp - bp repulsion (C) Both are equally stable due to 2 lp-bp repulsions (D) Both are unstable since SF4 has tetrahedral shape

In structure (ii), lp-bp repulsions are minimum.

Q. Which of the following shapes of $S F_{4}$ is more stable and why?

$(i)$ , due to $3 lp - b p$ repulsions at $9 0^{\circ}$

$(ii)$ , due to $2 lp - b p$ repulsion

Both are equally stable due to $2 lp - b p$ repulsions

Both are unstable since $S F_{4}$ has tetrahedral shape

In structure $(ii), lp - b p$ repulsions are minimum.

Q. Which of the following shapes of SF4​ is more stable and why?

(i), due to 3lp−bp repulsions at 90∘

(ii), due to 2lp−bp repulsion

Both are equally stable due to 2lp−bp repulsions

Both are unstable since SF4​ has tetrahedral shape
