Dinitrogen is a robust compound, but reacts at hig altitude to form oxides. The oxide of nitrogen the can damage plant leaves and retard photosynthes is

Options

  1. ANO
  2. BNO 3 -
  3. CNO 2
  4. DNO 2 -

Correct answer

C. NO 2

Step-by-step solution

Dinitrogen and dioxygen are the main constituents of air. These gases do not react with each other at a normal temperature. At high altitudes when lightning strikes, they combine to form oxides of nitrogen. N 2 g + O 2 g → 2 NO g NO reacts instantly with oxygen to give NO 2 2 NO g + O 2 g → 2 NO 2 g Rate of production of NO 2 is faster when nitric oxide reacts with ozone in the stratosphere The irritant red haze in the traffic and congested places is due to oxides of nitrogen. Higher concentrations of N
