Question

Which of the following statements is true for $I{O}_2{F}_2^{-}$?

• A. The lone pairs are located in the equatorial positions
• B. It is $s{p}^{3}d$ hybridised and is T-shaped
• C. Its structure is analogous to $S{F}_4$
• D. Both (A) and (C)

Answer 1

The correct option is D Both (A) and (C)

Steric Number (SN) for the central atom
$=$ Number of bonded atoms $+$ number of lone pairs

So, SN $=4+1=5$
$\to$ $I{O}_2{F}_2^{-}$ ion is $s{p}^{3}d$ hybridized.

Due to the presence of a lone pair at one of the equatorial positions, the shape is see-saw.
