On heating lead (II) nitrate gives a brown gas " A". The gas " A" on cooling changes to colourless solid "B" . Solid B on heating with NO changes to a blue solid 'C . Identify ' A', 'B' and' C and also write reactions involved and draw the structures of 'B' and 'C' .

Text Solution

Verified by Experts

`Pb(NO_(3))_(2)` on heating produces a brown coloured gas which may be `NO_(2)`. Since , on reaction with `N_(2)O_(4)` and on heating it produces `N_(2)O_(3)` and `N_(2)O_(4)` respectively.
Structures
(i) `N_(2)O_(4)` , (ii) `N_(2)O_(3)`
