Question

In which species, the hybrid state of central atom is are $s{p}^{3}d$ hybirdization?

• A. $I_3^{⨁}$
• B. $S{F}_4$
• C. $P{F}_5$
• D. $I{F}_5$

Answer 1

Answer: (B), (C)

The correct options are
B $S{F}_4$
C $P{F}_5$

$I_3^{+}$ is $s{p}^3$ hybridised with two bond pairs and two lone pairs.

$S{F}_4$ is $s{p}^{3}d$ hybridised with four bond pairs and one lone pair.

$P{F}_5$ is $s{p}^{3}d$ hybridised with five bond pairs.

$I{F}_5$ is $s{p}^3{d}^2$ hybridised with five bond pairs and one lone pair.
