Question

In the crystalline state, $PC{l}_5$ shows which of the following hybridization/s?

• A. $s{p}^3$
• B. $s{p}^2$
• C. $s{p}^{3}d$
• D. $s{p}^3{d}^2$

Answer 1

Answer: (A), (D)

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

In crystalline state, $PC{l}_5$ is present as $\left[PC{l}_4{]}^{+}\right[PC{l}_6{]}^{-}$ in which the cation is $s{p}^3$ hybridised and anion is $s{p}^3{d}^2$ hybridised.
