Question

Dinitrogen is a robust compound, but reacts at high altitudes to form oxides. The oxide of nitrogen that can damage plant leaves and retard photosynthesis is ______.

विकल्प

• NO

• `"NO"_3^-`

• NO₂

• `"NO"_2^-`

Answer 1

Dinitrogen is a robust compound, but reacts at high altitudes to form oxides. The oxide of nitrogen that can damage plant leaves and retard photosynthesis is NO₂.

Explanation:

\[\ce{N2(g) + O2(g) -> 2NO(g)}\]

\[\ce{2NO(g) + O2(g) -> 2NO2(g)}\]

Higher concentration of NO₂ damage the leaves and retard the rate of photosynthesis.
