Question

The structure of PCl₅ in the solid state is ______.

Options

• tetrahedral [PCl₄]⁺ and octahedral [PCl₆]⁻

• trigonal bipyramidal

• square planar [PCl₄]⁺ and octahedral [PCl₆]⁻

• square pyramidal

Answer 1

The structure of PCl₅ in the solid state is tetrahedral [PCl₄]⁺ and octahedral [PCl₆]⁻.

Explanation:

\[\ce{2PCl5_{(s)} -> \underset{Tetrahedral}{[PCl4]+} \underset{Octahedral}{[PCl6]-}}\]
