Which of the following reactions will deplete `O_(3)` layer?

Options

A. `HOC ioverset(hv)(rarr)Ooverset(.)H+overset(.)Cl`
B. `Cl_(2)overset(hv)(rarr)overset(.)Cl`
C. `CF_(2)Cl_(2) overset(hv)CF_(2)Coverset(.)l+overset(.)Cl`
D. All of these

Answer

D

Explanation

`HOCl,Cl_(2)` and `CF_(3)Cl_(2)` are photolysed by sunlight generating `Coverset(.)(l)` radicals, which deplete `O_(3)` layer.
`O_(3)+Coverset(.)(l)+O_(2)`
`Cloverset(.)(O) + O rarr Coverset(.)(l)+O_(2)`.
