NEET Chemistry Physical Properties Assertion Reason Question
Given below are two statements : Statement-I : The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole-dipole interactions. Statement-II : The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of H⁻bonding. In the light of the above statements, choose the most appropriate answer from the options given below:
Both statement-I and statement-II are correct.
Both statement-I and statement-II are incorrect.
Statement-I is correct but statement-II is incorrect.
Statement-I is incorrect but statement-II is correct.
Correct Answer
Detailed Explanation
Both statements are correct as aldehydes and ketones have higher boiling points than hydrocarbons due to dipole interactions, but lower than alcohols due to lack of hydrogen bonding.
