Two oxides of nitrogen, NO and N O 2 are allowed to react together at 243 K and form coloured compound of nitrogen (X). When compound (X) reacts with water to yield another compound of nitrogen (Y). The shape of the anion (Y) molecule is
Options
- Aangular
- Btriangular pyramidal
- Ctetrahedron
- Dsquare planar
Correct answer
A. angular
Step-by-step solution
Here X is N 2 O 3 (light blue coloured) and Y is Nitrous ( H N O 2 ) acid NO (g) + NO 2 (g) → 243 K N 2 O 3 X Blue coloured solid → H 2 O HNO 2 Y Anion of HNO 2 is NO 2 − and it is a angular or bent in shape
