The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that "Alcohols have higher boiling points than ethers of comparable molecular masses." - **Explanation**: Alcohols (like ethanol, CH3CH2OH) have a hydroxyl (-OH) group that allows them to form strong hydrogen bonds with each other. Ethers (like dimethyl ether, CH3OCH3), on the other hand, do not have a hydrogen atom bonded to oxygen, which limits their ability to form hydrogen bonds. As a result, alcohols generally have higher boiling points than ethers when comparing compounds of similar molecular weights. ### Step 2: Understand the Reason The reason states that "Alcohols and ethers are isomeric in nature." - **Explanation**: Isomerism refers to compounds that have the same molecular formula but different structures or functional groups. In this case, ethanol (C2H6O) and dimethyl ether (C2H6O) are isomers of each other. However, while they are isomers, the reason does not directly explain why alcohols have higher boiling points than ethers. ### Step 3: Conclusion - The assertion is **true**: Alcohols do have higher boiling points than ethers of comparable molecular masses due to stronger hydrogen bonding. - The reason is also **true**: Alcohols and ethers can be isomers of each other. - However, the reason does not adequately explain the assertion. ### Final Answer Thus, the correct answer is: **B**: The assertion is correct, but the reason is not the correct explanation of the assertion. ---
