Question

Polar stratospheric clouds facilitate the formation of ______.

विकल्प

• ClONO₂

• HOCl

• ClO

• CH₄

Answer 1

Polar stratospheric clouds facilitate the formation of HOCl.

Explanation:

Polar stratospheric clouds provide a surface for the hydrolysis of ClONO₂ to form HOCl (Hypochlorous acid).

\[\ce{ClONO2(g) + H2O(g) -> HOCl(g) + HNO3(g)}\]
