Assertion : `PCl_(5)` is covalent in gaseous and liquid state but ionic in solid state.
Reason: `PCl_(5)` in solid state consists of tetrahedral `PCl_(4)^(+)` cation and octahedral `PCl_(6)^(-)` anion.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
`PCl_5` is covalent in gaseous and liquid state. P atom is connected to 5`gamma` bonds with Cl atoms. But in solid state `PCl_5` consist of tetrahedral `[PCl_4]^+` cation and octahedral `[PCl_6^(-)]` anion. Hence in solid state it is ionic.
