Question

Ozone layer of upper atmosphere is being destroyed by :

Chlorofluorocarbon

SO2

Photochemical oxidants/O2& CO2

Smog

Answer

Chlorofluorocarbon

Explanation

Solution

Chlorofluoro carbons (CFC's) come in contact with atmospheric gases and enventually reach stratosphere where they cause depletion in ozoen layer.

CF2Cl2(g) $\overset{\quad uv\quad}{\rightarrow}C\overset{\bullet}{l}(g) + \overset{\bullet}{C}F_{2}Cl(g)$ ; $\overset{\bullet}{C}$ l + O3 $\longrightarrow$ Cl $\overset{\bullet}{O}$ (g) + O2(g) ; Cl(g) $\overset{\bullet}{O}$ $\longrightarrow$ $\overset{\bullet}{C}$ l(g) + O2(g)
