1.	PCl_(5) is ionic in nature in the solid state. Give reasons. Or Solid phosphorus pentachloride behaves as an inoic compound. Explain.
Answer» SOLUTION :`PCl_(5)` CONDUCTS electricity in the molten state. This means that in the solid state, it exists as `[PCl_(6)]^(+)[PCl_(6)]^(-)` in which the CATION is tetrahedral and the anion is octahedral `2PCl_(5)to[PCl_(4)]^(+)[PCl_(6)]^(-)` On melting these ions become free to move and hence `PCl_(5)` conducts electricity in the molten state.
