Question

Which of the following statements is true for IO${}_2$F${{}_2}^{-}$ according to VSEPR theory?

• A. The lone pair and two I - O double bonds occupy the equatorial positions of trigonal bipyramid
• B. It has sp${}^3$d hybridisation and is T-shaped
• C. Its structure is analogous to SF${}_4$
• D. (A) and (C) both

Answer 1

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

The structure of ${I{O}_2{F}_2}^{-}$ is given. The lone pair of electrons and the $I-O$ double bonds occupy the equatorial positions of the trigonal bipyramid. The more electronegative F atoms occupy the axial positions. Also, its structure is analogous to $S{F}_4$ as is clear from their structures shown.
