Question

Hybridization of central I in $I_3^{-}$ is :

• A. $sp$
• B. $s{p}^2$
• C. $s{p}^3$
• D. $s{p}^{3}d$

Answer 1

The correct option is D $s{p}^{3}d$

$Stericnumber,S.N.=\frac{1}{2}\times (V+M-C+A)$
$S.N.=\frac{1}{2}\times (7+2-0+1)$
$S.N.=\frac{1}{2}\times (7+2+1)$
$S.N.=5$
Hybridisation = $s{p}^{3}d$
