2022 1 question

1. Given below are two statements: Statement I: The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular mass 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 mass due to the absence of H-bonding. In the light of the above statements, choose the most appropriate answer from the options given below:
