The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement individually and determine their correctness. ### Step-by-Step Solution: 1. **Evaluate Statement 1**: - The statement claims that "Sulphuric acid is less viscous than water due to intermolecular hydrogen bonding." - To assess this, we need to understand the viscosity of both substances. Viscosity is a measure of a fluid's resistance to flow. - Sulphuric acid (H₂SO₄) has strong intermolecular hydrogen bonding due to the presence of hydroxyl groups (–OH) in its structure. This strong hydrogen bonding leads to a higher viscosity compared to water. - Therefore, the statement is incorrect. Sulphuric acid is actually **more viscous** than water due to these strong intermolecular forces. 2. **Evaluate Statement 2**: - The second statement asserts that "Concentrated sulphuric acid is used as a dehydrating agent." - A dehydrating agent is a substance that removes water from other compounds. - Concentrated sulphuric acid is well-known for its ability to absorb water and remove water molecules from organic compounds. For example, it can dehydrate carbohydrates like sucrose (C₁₂H₂₂O₁₁) to form carbon and water. - Thus, this statement is correct. Concentrated sulphuric acid is indeed used as a dehydrating agent. 3. **Conclusion**: - Statement 1 is **false** (sulphuric acid is more viscous than water). - Statement 2 is **true** (concentrated sulphuric acid is a dehydrating agent). - The correct option based on the evaluation is that Statement 1 is false and Statement 2 is true. ### Final Answer: - Statement 1: False - Statement 2: True - Correct option: Statement 1 is false and Statement 2 is true. ---
