Chemistry - CHEMICAL BONDING Question with Solution | TestHub

For X=P, Z=Cl, and Y=[PCl₆]⁻, solid PCl₅ consists of [PCl₄]⁺ and [PCl₆]⁻ ions. Condensation of two H₃PO₄ molecules yields H₄P₂O₇, which features a P-O-P bridge (Option A).

Cl₂O₆ does not possess a peroxy linkage, making statement B false. The terminal and bridging oxygen atoms in Cl₂O₇ do not all exhibit sp³ hybridization, thus statement C is false. A tetrahedral [PCl₄]⁺ ion allows a maximum of three of its five atoms to lie in a single plane (Option D).

Therefore, the correct answers are A and D.
