Question

$s{p}^3{d}^2$ hybridization is not displayed by :

• A. $\mathrm{BrF}{}_5$
• B. $\mathrm{SF}{}_6$
• C. $[\mathrm{CrF}{}_6]{}^{3-}$
• D. $\mathrm{PF}{}_5$

Answer 1

Answer: (D)

$s{p}^3{d}^2$ hybridization is not displayed by $P{F}_5$. The central $P$ atom has 5 sets of electron pairs (all of which are bonding) and $s{p}^3{d}^2$ hybridization corresponds to 6 sets of electron pairs.
