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. |

Answer» Solution :(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]^(-)`. |
