Question

The hybridizations of the cation and the anion respectively, when $PC{l}_5$ exists as a solid are:

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

Answer 1

The correct option is B $s{p}^{3}ands{p}^3{d}^2$

In solid state, $PC{l}_5$ exists as $\left[PC{l}_4{]}^{+}and\right[PC{l}_6{]}^{-}$ which are $s{p}^3$ and $s{p}^3{d}^2$ hybridised respectively.
