Question

HCFC refrigerants cause ____________ damage to the stratospheric ozone layer in comparison to CFC refrigerants.

Answer 1

HCFC refrigerants cause less damage to the stratospheric ozone layer compared to CFC refrigerants.

Step-by-step explanation:

HCFC refrigerants cause less damage to the stratospheric ozone layer in comparison to CFC refrigerants. This is because HCFCs, such as CHCl₂CF3, break down more readily in the troposphere, and fewer ozone-destroying molecules reach the stratosphere.

CFCs, on the other hand, decompose in the presence of ultraviolet light and produce atomic chlorine, which reacts with ozone molecules, resulting in a net removal of ozone from the stratosphere.
