Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The dissociation of Cl₂O₆ yields ClO₂⁺ (X) and ClO₄⁻ (Y).

X (ClO₂⁺) is angular (bent), not planar.

Y (ClO₄⁻) is tetrahedral.

In ClO₂⁺, p$\pi$-p$\pi$ and p$\pi$-d$\pi$ bonds are present.

In ClO₄⁻, all Cl-O bond lengths are same due to resonance.

ClO₂⁺ has 1 lone pair on Cl. ClO₄⁻ has 0 lone pairs on Cl. So, the total number of lone pairs are not the same. Thus, D is NOT CORRECT.
