हिन्दीGiven 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:
Correct answer · Option 3
Both Statement I and Statement II are correct.
Explanation
Both statements are factually correct. Aldehydes and ketones have dipole-dipole interactions leading to higher boiling points than hydrocarbons, but lack intermolecular H-bonding present in alcohols.
