Question

Quizplus · Accepted Answer

HCFCs have been used as a temporary solution to the problem of ozone depletion as they have lower ozone depletion potentials than CFCs. However, HCFCs still contain chlorine and contribute to ozone depletion. Therefore, the goal is to replace them with compounds that do not contain chlorine. HFCs (hydrofluorocarbons) are a class of compounds that do not contain chlorine and have been identified as a suitable replacement for HCFCs. The phase-out of HCFCs is already underway, and it is expected that HFCs will be widely used as a replacement over the next 20 years.
