(A): Ozone is an allotrope of oxygen.
(R): Ozone is better oxidising agent as compared with oxygen. 

Options

A. Both A & R are true, R is the correct explanation of A
B. Both A & R are true, R is not correct explanation of A
C. A is true, R is false
D. A is false, R is true

Answer

To analyze the given statements about ozone and oxygen, we will break down the information step by step.

### Step-by-Step Solution:

1. **Understanding Allotropes**:
- Allotropes are different forms of the same element that exist in the same physical state.
- Oxygen exists in different allotropes, primarily dioxygen (O2) and ozone (O3).

**Hint**: Recall the definition of allotropes and think of examples beyond oxygen.

2. **Identifying the Allotropes**:
- Ozone (O3) is indeed an allotrope of oxygen. It consists of three oxygen atoms bonded together.
- Dioxygen (O2) consists of two oxygen atoms.

**Hint**: Consider the molecular formulas of different forms of oxygen to confirm their allotropy.

3. **Evaluating the Oxidizing Power**:
- An oxidizing agent is a substance that can accept electrons and, in the process, oxidize another substance.
- Ozone is known to be a stronger oxidizing agent than dioxygen (O2) due to its ability to release nascent oxygen (O) when it decomposes.

**Hint**: Think about the chemical reactions involving ozone and how they differ from those involving dioxygen.

4. **Chemical Reaction of Ozone**:
- When ozone decomposes, it produces dioxygen and nascent oxygen, which is highly reactive and contributes to its strong oxidizing properties.

**Hint**: Review the decomposition reaction of ozone to see how it generates nascent oxygen.

5. **Conclusion on Statements**:
- Statement (A): "Ozone is an allotrope of oxygen" is **True**.
- Statement (R): "Ozone is a better oxidizing agent as compared with oxygen" is also **True**.
- However, (R) does not explain (A); it provides additional information about the properties of ozone.

**Hint**: Analyze the relationship between the two statements to determine if one explains the other.

### Final Answer:
Both statements (A) and (R) are true, but (R) is not the correct explanation for (A).
