Give reasons for the following:
(a) Nitric oxide becomes brown when released in air.
(b) `PCI_5` is ionic in nature in the solid state.

Text Solution

Verified by Experts

(a) NO reacts with `O_2` of air to form nitrogen dioxide which is brown in colour.
`2NO + O_2 to 2NO_2` (brown )
(b) `PCl_5` is ionic in nature in solid state because it exists as `[PCl_4]^(+)[PCl_6]^(-)`.
