Question

Which of the following best describes the effects of using

Answer 1

Answer:

Option D, HFCs and HCFCs are less likely to deplete stratospheric ozone and contribute less  to global warming than CFCs do

Explanation:

HFCs have the ability to replace CFCs. They are able to deplete the stratospheric ozone because they have chlorine. However, their ozone depletion potentials (ODPs) is quite less as compared to that of CFCs. HCFCs ozone depletion potentials (ODPs) is between 0.01 to 0.1 while that of CFCs is around 1. Hence, HCFCs deplete less  stratospheric ozone and hence their contribution to global warming is comparatively low

Hence, option D is correct
