Question

The type of hybrid orbital usedby the Cl atiom in $Cl{O}_2^{-}$

• A. $s{p}^2$
• B. $sp$
• C. $s{p}^3$
• D. None of the above

Answer 1

The correct option is C $s{p}^3$

Steric Number $\left(x\right)$ = $\frac{1}{2}\left(M+V-C+A\right)$.
where, M = number of monovalent surrounding atoms
V = number of valence electrons on the central atom
C = charge (with sign)
A=charge on anion
$Cl{O}_2^{-}$
$\text{Steric Number (x)}=\frac{1}{2}(0+7-0+1)$.
$\text{Steric Number (x)}=4$.
Hybridisation =$s{p}^3$
