Question

Structure of $I{F}_4^{+}$ and hybridization of iodine in this structure are

• A. $s{p}^3{d}^2$, Linear
• B. $s{p}^3{d}^2$, T-shaped
• C. $s{p}^{3}d$, Irregular tetrahedral
• D. $s{p}^3{d}^2$, Octahedral

Answer 1

The correct option is C

$s{p}^{3}d$, Irregular tetrahedral

Lets try to find out ep value and then geometry.

$I{F}_4^{+}\Rightarrow$ ep = $\frac{(7+4-1)}{2}$ = 5[Trigonal Planar]

Ep = 5 $\Rightarrow s{p}^{3}d$ hybridization

Because F is most electronegative, lone pair and F (equatorial plane) will repel each other.

If will make Irregular Tetrahedral.
