HCFCs have been developed to replace CFCs as refrigerants.Which property of these new compounds makes them environmentally superior to CFCs?
A)Greater reactivity leads to decomposition at elevations below the stratospheric ozone concentration maximum
B)Lower reactivity makes them stable even in the intense ultraviolet light in the stratosphere
C)Their higher molecular weight prevents them from reaching the stratosphere
D)They do not contain chlorine

Question

Quizplus · Accepted Answer

HCFCs (Hydrochlorofluorocarbons) are considered environmentally superior to CFCs (Chlorofluorocarbons) because their greater reactivity allows them to decompose in the lower atmosphere, preventing them from reaching the stratosphere where they could deplete ozone.
