Asserartion:PCl(5) is covalent in gaseou...

Asserartion:`PCl_(5)` is covalent in gaseous and liquide states but ionic in solid state.
Reason: `PCl_(5)` in solid state consits of tetrahhedral `PCl_(4)^(+)` cation and octahedral `PCl_(6)^(-)` anion.

A

If both assertion and reason are true and reason is the true explanation of the asseraton.

B

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

C

If assertion is true bit reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
Both asseration and reason are true and the reason is the correct explanation of the asseration.
`PCl_(5)` is trigonal bipyramidal containing `PCl_(4)^(+)` hybridized P atom in liquid and gaseous state. Whereas in solid state it consists of tetrahedral `PCl_(4)^(+)` cation and octahedral `PCl_(6)^(-)` anion.
