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

  1. Aangular
  2. Btriangular pyramidal
  3. Ctetrahedron
  4. 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
