State the role of chlorofluorocarbons in ozone destruction or depletion [no equations required].

उत्तर
Roll of chlorofluorocarbons in ozone destruction : Chlorofluorocarbons are decomed by U.R. rays and liberate highly reactive free CF radical. This free ladical reacts with ozone to form Cl0[g]. This causes ozone depletion. The Cl free radicals initiate and catalyse a chain reaction – capable of breakdown of over 1,00,000 ozone molecules resulting in ozone depletion.
