AIIMS 2018 Chemistry Physical Properties of Organic Compounds Assertion Reason Question
Assertion: Aldehyde have lower boiling point than ether. Reason: Aldehydes are less polar than ether
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Both the assertion and reason are false. Aldehydes generally have higher boiling points than ethers due to the presence of polar carbonyl (C=O) groups that can engage in dipole-dipole interactions, while ethers primarily exhibit weaker Van der Waals forces. Additionally, aldehydes are not less polar than ethers; in fact, they are more polar due to the electronegativity of the oxygen in the carbonyl group. Therefore, options A, B, and C are incorrect as they rely on the assertion and reason being true or correctly related, which they are not.
