Question

The most stable shape of $Cl{F}_3$ is shown by

• A. $(i)$ only
• B. $(i)$ and $(iii)$
• C. $(ii)$ only
• D. $(iii)$ only

Answer 1

Answer: (A)

In $(i)$, the $lp$ are at equatorial position so there are less $lp-bp$ repulsions as compared to other positions. Hence, $T$-shape is most stable.
