Question

Dinitrogen is a robust compound, but reacts at high altitude to form oxides. The oxide of nitrogen that can damage plant leaves and retard photosynthesis is : 3– 2 2– 2 2 2 2 2 2

(A) NO
(B) NO
(C) NO
(D) NO

Prashant Kotian · Accepted Answer

Correct answer: A) NO. When fossil fuel is burnt nitrogen and dioxygen combine to yield significant quantities of nitric oxide (NO) and nitrogen dioxide (NO ) as given below : N (g) + O (g) 2NO(g) 2NO(g) + O (g) 2NO (g) Higher concentration of NO damage the leaves of plants and retard the rate of photosynthesis.
