Question

The structure of $PC{l}_5$ in the solid state is

• A. square pyramidal
• B. tetrahedral ${\left[PC{l}_4\right]}^{+}$ and octahedral ${\left[PC{l}_6\right]}^{-}$
• C. square planar ${\left[PC{l}_4\right]}^{+}$ and octahedral $\left[PC{l}_6\right]$
• D. trigonal bipyramidal

Answer 1

Answer: (B)

$PC{l}_{5(s)}$ exist as ${\left[PC{l}_4\right]}^{+}$ and ${\left[PC{l}_6\right]}^{-}$
