Q. Which of the following shapes of $SF_{4}$ is more stable and why?
Chemical Bonding and Molecular Structure
A
$(i)$, due to $3\, lp-bp$ repulsions at $90^\circ$
18%
B
$(ii)$, due to $2\, lp - bp$ repulsion
52%
C
Both are equally stable due to $2 lp-bp$ repulsions
11%
D
Both are unstable since $SF_4$ has tetrahedral shape
19%
Solution:
In structure $(ii), lp-bp$ repulsions are minimum.
