Question

According to VSEPR theory in $[I{O}_2{F}_2{]}^{-}$ ion, the $F-\hat{I}-F$ bond angle will be nearly:

• A. ${120}^0$
• B. ${90}^{0}C$
• C. ${109}^0{28}^{\prime }$
• D. ${180}^0$

Answer 1

The correct option is D ${180}^0$

Ther will be repulsion between loan pair and bond pair So $F\hat{I}F$ will be slightly less than ${180}^0$.

So It will be nearly ${180}^0$.

Structure of $I{O}_2{F}_2^{-}$ is as shown.
