Question

The molecular formula of ozone is

• A. O$_2$
• B. O$_3$
• C. O$_4$
• D. O$_5$

Hint:

Ozone is a protective shield in the stratosphere but harmful at ground level, where it acts as a pollutant.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Oxygen exists in different molecular forms (allotropes).
O$_2$: Normal diatomic oxygen we breathe.
O$_3$: Ozone, a triatomic form of oxygen.
Step 2: Detailed Explanation:
Ozone is made up of three oxygen atoms bonded together. It forms naturally in the stratosphere and protects life on Earth by absorbing harmful ultraviolet (UV) radiation.
Step 3: Final Answer:
The molecular formula of ozone is O$_3$.
