Which of the following statements are incorrect?

Options

A. Solid `PCl_5` exists as tetrahedral `[PCl_4]^(+)` and octahedral `[PCl_6]^(+)` ions.
B. Oxides of phosphorus, `P_2 O_3 and P_2 O_3` exist as monomers.
C. Solid `PCl_5` exists as `[PCI_4]^(+)CI^(-)`
D. Solid `N_2 O_5` exists as `NO_(2)^(+) NO_(3)^(-)`

Answer

B, C

Explanation

Oxides of phosphorus `P_2 O_3` and `P_2 O_5` exist as dimers, that is, `P_2 O_6 ` and `P_4 O_(10)` Solid `PCl_5`, exists as `[PCI_4]^(+) and [PCI_6]^(-)` .
