Problem

According to VSEPR model, molecules adopt geometries in which their valence electron pairs position themselves as far from each other as possible. The VSEPR model considers double and triple bonds to have slightly greater repulsive effects than single bonds because of the repulsive effect of

\pi

-electrons. However the lone pair creates the maximum repulsive effect. Which of the following does not represent the isostructural pair? (1)

\text{SF}_5^-

and

\text{IF}_5

(2)

\text{ClO}_2\text{F}_3

and

\text{SOF}_4

(3)

\text{SeF}_3^+

and

\text{XeO}_3

(4) None
