Answer 2

Chlorine

Step-by-step explanation:

Chlorine is a major component of chlorofluorocarbons. These chemicals contain a C-Cl bond which can be broken by absorption of ultraviolet radiation. The free Cl^. radical now attacks stratospheric ozone reducing it to oxygen and forming chlorine monoxide. This destroys ozone present in the stratosphere. Hence the call for substitution of chlorofluorocarbons in order to save the ozone layer. Adjustments to chlorofluorocarbons use was contained in the Montreal protocol.
