Question
Chapter 11, Problem 34E
Interpretation Introduction
Interpretation:
The result of CFC ban on the Antarctic ozone hole is to be explained.
Concept Introduction:
HCFCs and CFCs are a class of inert compounds of carbon, chlorine, and fluorine. They are quite useful for many applications but the inertness of CFCs has an environmental effect. It made a hole in the ozone layer, which was the biggest environmental concern. Hence, it was banned in 1978.
