Which of the following would react with ozone in the atmosphere?
Correct answer: D. Cl*
- A. F*
- B. O2
- C. O*
- D. Cl*
Explanation
Chlorine and bromine atoms are also known as free radicals. Other free radicals in the stratosphere can also remove ozone. The chlorine atoms react with ozone to produce chlorine oxide and O2 molecules. The chlorine oxide molecule is also very reactive and can react with oxygen atoms to regenerate the chlorine atom, hence catalysing the destruction of the ozone layer.
