MCQ
Which of the following is a photochemical reaction product?
- AFlourides
- B$\text{CO}$ and $\mathrm{CO}_2$
- C$\mathrm{SO}_3$
- ✓$\mathrm{O}_3$

Answer
Correct option: D.
$\mathrm{O}_3$
The ozone molecule is formed due to the action of the $\text{UV}$ rays with the oxygen molecules. When the $\text{UV}$ rays penetrate in the Earth's atmosphere, the radiations react with the $\mathrm{O}_2$ molecule to form oxygen atoms which react again to form $\mathrm{O}_3$. This reaction is known as photochemical reaction in which light and radiations form ozone.
