[Adrian C 1D]

A)What is the shape of a ClO2+ ion?
B)What is the expected OCLO bond angle?

I know the bond angle would not be 180 degrees since the shape is not linear, but the answer says it is slightly less than 120 degrees. How did they arrive at this answer?

Because the molecule has lone pairs, it is bent

If you draw out the Lewis structure for ClO₂⁺, you will see that Cl is attached to one O by a double bond and the other by a single bond while Cl has a lone pair. The VSEPR formula for ClO₂⁺ is AX₂E₁ which has bond angles slightly <120^o
