The correct Answer is:
To solve the question, we will analyze both the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that "Boiling points of alcohols are higher than ethers." We need to evaluate whether this statement is true. **Hint:** Consider the molecular structure and properties of alcohols and ethers. ### Step 2: Compare Boiling Points Alcohols, such as ethanol (C2H5OH), can form hydrogen bonds due to the presence of the hydroxyl (-OH) group. Ethers, like dimethyl ether (C2H6O), do not have a hydroxyl group and cannot form hydrogen bonds. **Hint:** Recall the role of hydrogen bonding in determining boiling points. ### Step 3: Explain the Reason The reason states that "They can form intermolecular hydrogen bonding." This is true for alcohols but not for ethers. The ability to form hydrogen bonds leads to stronger intermolecular forces in alcohols compared to ethers. **Hint:** Think about how intermolecular forces affect the physical properties of substances. ### Step 4: Conclusion on Assertion and Reason Since the assertion is true (boiling points of alcohols are indeed higher than those of ethers), and the reason is also true (alcohols can form hydrogen bonds), we need to determine if the reason correctly explains the assertion. **Hint:** Assess whether the reason provided directly supports the assertion made. ### Step 5: Final Answer Both the assertion and the reason are correct, and the reason is a correct explanation for the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation for the assertion. **Final Answer:** Option 1: Both Assertion and Reason are correct, and the Reason is the correct explanation for the Assertion.
