HFCs (Hydrofluorocarbons) and HCFCs
(Hydrochlorofluorocarbons) were developed as alternates for CFCs to mitigate
ozone layer depletion. Why will they not cause ozone layer depletion?

Question

Accepted Answer

c.  They will not reach the stratosphere as they
contain H atoms which react with the hydroxyl radicals of the lower atmosphere

Answer

a.  They will reach the stratosphere, but they
contain H atoms that reduce the molecular weight of the compound and they go
further up above the stratosphere

Answer

b.  They
will not reach the stratosphere as they contain H atoms which react with the
oxygen of the lower atmosphere.

Answer

d.  They will reach the stratosphere, but they contain H atoms which react with the
chlorine atoms of the stratosphere. Hence, chlorine will not react with Ozone
