Question

Ozone in stratosphere is depleted by (A)  CF2Cl2  (B)  C7F16  (C)  C6H6Cl6 (D)  C6F6

Tardigrade Admin · Accepted Answer

Chlorofluorocarbons (CFCs or freons like

C F_{2} / C l_{2}

) are responsible for depletion of the ozone layer in the upper strata of atmosphere. They are stable and inert compounds. They absorb UV-rays and break down liberating free atomic chlorine which causes depletion of ozone through free radical reaction.

\dot{C} l + O_{3} ⟶ Cl \dot{O} + O_{2}

Cl o^{\circ} + O_{3} ⟶ \dot{C} + 2 O_{2}
