Question

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

• A. $[Cr{F}_6{]}^{3-}$
• B. $S{F}_6$
• C. $P{F}_5$
• D. $Br{F}_5$

Answer 1

Answer: (C)

$P{F}_5$

$s{p}^3{d}^2$ 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.
