This section contains Assertion and Reason type question each question has 4 choices (1)(2)(3)(4) out of which only one is correct
Assertion(A):The structure `H_2O` is similar to `SO_2`
Reason(R):in both molecules the central atom has one lone pair of electron

Options

A. Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion
C. Assertion is correct but Reason is incorrect
D. Both Assertion and Reason are incorrect

Answer

To solve the assertion and reason question, we will analyze both the assertion (A) and the reason (R) step by step.

### Step 1: Analyze the Assertion (A)
**Assertion (A):** The structure H₂O is similar to SO₂.

- **H₂O (Water):** The molecular geometry of water is bent due to the presence of two lone pairs of electrons on the oxygen atom. The bond angle is approximately 104.5°.
- **SO₂ (Sulfur Dioxide):** The molecular geometry of sulfur dioxide is also bent due to the presence of one lone pair of electrons on the sulfur atom. The bond angle is approximately 120°.

**Conclusion for Assertion:** Both molecules have a bent shape, which suggests that the assertion is correct.

### Step 2: Analyze the Reason (R)
**Reason (R):** In both molecules, the central atom has one lone pair of electrons.

- **For H₂O:** The central atom (oxygen) has two lone pairs of electrons.
- **For SO₂:** The central atom (sulfur) has one lone pair of electrons.

**Conclusion for Reason:** The reason is incorrect because H₂O has two lone pairs, while SO₂ has one lone pair.

### Step 3: Determine the Correct Option
Given the analysis:
- The assertion is correct.
- The reason is incorrect.

Thus, the correct option is **(3)**: Assertion is correct, and reason is incorrect.

### Final Answer:
**Option (3): Assertion is correct and reason is incorrect.**
