Question

The geometry of electron pairs around $I$ in $I{F}_5$ is:

• A. Octahedral
• B. Trigonal bipyramidal
• C. Square pyramidal
• D. Pentagonal planar

Answer 1

The correct option is A Octahedral

Geometry of $I{F}_5$ :
Steric number of $I{F}_5$ = $\frac{1}{2}(7+5)=6$
So, the number of bond pairs and lone pairs are 5 and 1 respectively. The hybridisation is $s{p}^3{d}^2$.

$\therefore$ The geometry loooks like
$\therefore$ the geometry is octahedral and the shape of molecule is distorted square pyramidal.
