Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Solid Cl₂O₆ exists as [ClO₂]⁺[ClO₄]⁻. The cationic part is ClO₂⁺.

Hybridization of Cl in ClO₂⁺:

Valence electrons of Cl = 7

Valence electrons of O = 6

Charge = +1

Total valence electrons = $7+2(6)-1=18$ electrons.

Number of electron pairs = $18/2=9$ pairs.

Central atom is Cl.

Structure: O=Cl=O with one lone pair on Cl.

Steric number = (number of sigma bonds) + (number of lone pairs) = $2+1=3$.

Therefore, the hybridization is sp².
