Assertion : Bond angle in `H_(2)O` is less than that in `H_(2)S`.
Reason : Electronegativity of O is more than that of S.

Options

A. Assertion and reason both are correct statements and reason is correct explanation for assertion.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statement.

Answer

To solve the question, we need to analyze the assertion and reason provided:

### Step 1: Understand the Assertion
The assertion states that the bond angle in H₂O is less than that in H₂S.

- **H₂O (Water)** has a bond angle of approximately 104.5 degrees.
- **H₂S (Hydrogen Sulfide)** has a bond angle of approximately 92.1 degrees.

### Step 2: Compare the Bond Angles
To compare the bond angles, we note that H₂O has a higher bond angle than H₂S. Therefore, the assertion is incorrect.

### Step 3: Understand the Reason
The reason states that the electronegativity of oxygen is more than that of sulfur.

- The electronegativity of oxygen is approximately 3.5 (on the Pauling scale), while that of sulfur is about 2.5.

This statement is correct.

### Step 4: Conclusion
Since the assertion is incorrect (H₂O has a larger bond angle than H₂S), but the reason is correct (oxygen is more electronegative than sulfur), the correct conclusion is:

- **Assertion is False**.
- **Reason is True**.

Thus, the correct answer is that the assertion is false while the reason is true.

### Final Answer:
The assertion is incorrect, and the reason is correct.
