Phosphorous form two types of halides PX...

Phosphorous form two types of halides `PX_3` and `PX_5` . Pentahalides are more covalent. Which is incorrect? (1)PCl3 is a colourless fuming liquid, prepared by action of white P4 on thionylchloride (2)PCl5 is an yellow/white crystalline solid with pungent smell obtained by action P4 with sulphuryl chloride(SO2Cl2),decomposes on heating and act only as oxidant. (3)In the solid state PCl5 exit as ionic solid. (4)PCl5 react with H20 to form PCl3 and HCl.

A

A. `PCI_3` is a colourless fuming liquid, prepared by action of white `P_4` on thionylchloride `(SOCI_2)`

B

B. `PCI_5` is an yellow/white crystalline solid with pungent smell obtained by action `P_4` with sulphuryl chloride `(SO_2CI_2)`, decomposes on heating and act only as oxidant

C

In the solid state `PCI_5` exist as ionic solid

D

`PCl_(5)` react with `H_(2)O` to form `PCI_3` and HCI
