Hydrochlorofluorocarbons (HCFCs) are human-made chemicals that have been used as temporary replacements for chlorofluorocarbons (CFCs) in refrigerants because they decompose more readily in the atmosphere and thus pose less of a threat to Earth’s protective ozone layer. Levels of HCFCs have been measured in the stratosphere, and the concentrations of many different HCFCs have been steadily increasing since the mid- to late 1990s.

One important drawback of the use of HCFCs as a replacement for CFCs is that HCFCs:

a) biomagnify in food chains in the Arctic ecosystem

b) combine with water vapor to form acid precipitation

c) are greenhouse gases that contribute to climate change

d) react with carbon monoxide ( CO ) to form ozone in the troposphere

The CFCs and the HCFCs are fully and partially hydrogenated carbons and contains carbon and hydrogen and chlorine and fluoride and other volatile substance and being a component of the greenhouses gases like the methane.

These contribute to climate change and the greenhouse effects on the earth and this is due to the government have phased put the use of CFCs and though this gas has a short lifespan.

It should be noted that one drawback of the use of HCFCs as a replacement for CFCs is that HCFCs is C. are greenhouse gases that contribute to climate change

It should be noted that CFCs and HCFCs contain carbon, hydrogen, chlorine, fluoride and other volatile substance and are a component of the greenhouses gases like methane.

They contribute to climate change and the greenhouse effects on the earth. This illustrates the drawback of the use of HCFCs as a replacement for CFCs.
