In solid state PCl₅ is a _________. 

(i) Covalent solid 

(ii) Octahedral structure 

(iii) Ionic solid with [PCl₆]⁺   octahedral and [PCl₄]⁻  tetrahedral

(iv) Ionic solid with [PCl₄]⁺  tetrahedral and [PCl₆]⁻  octahedral

This is a multiple choice answer as classified in NCERT Exemplar

Correct option is (iv)

The ionic bonding promotes the crystalline structure of PCl₅ in the solid state by attempting to exist as oppositely charged ions like  [PCl₄]⁺  and  [PCl₆]⁻ .  Also,   [PCl₄]⁺  and  [PCl₆]⁻  are tetrahedral and octahedral, respectively. These structures fit together well, giving the solid structure extra stability.
