Which of the following statement(s) is wrong?

1.  Ozone is not responsible for the greenhouse effect.
2.  Ozone can oxidize sulfur dioxide present in the atmosphere to sulfur trioxide.
3.  Ozone hole is thinning of the ozone layer present in the stratosphere.
4.  Ozone is produced in the upper stratosphere by the action of UV rays on oxygen.



 

Hint: 
Ozone can oxidize sulfur dioxide present in the atmosphere to sulfur trioxide is a true statement. 

The ozone hole is thinning of the ozone layer present in the stratosphere. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. It is true statement.

Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The reaction is as follows:



O3 is responsible for greenhouse effect. Its contribution is about 8%.
