In solid state PCl_(15)is a............

Answer»

Covalent SOLID
Octahedral structure
Ionic solid with [`PCl_6]^+` octahedral and `[PCl_4]^-` tetrahedral.
Ionic solid with `[PCl_4]`+ tetrahedral and `[PCl_6]^-` octahedral.

Solution :Due to weak P-Cl axial bond, in solid STATE `PCl_5` EXISTS as `[PCl_4]+ [PCl_6]^(-)` to attain stability.
`2PC_(5) to [PCl_(4)]^(+) + [PCl_(6)]^(-)`
