Vedclass · Answer

(A) Aldehydes and ketones possess a polar carbonyl group $(C=O)$,which creates a permanent dipole moment. Due to this polarity,there exist dipole-dipole interactions between the molecules of aldehydes and ketones. These intermolecular dipole-dipole interactions are stronger than the weak van der Waals forces present in hydrocarbons and ethers of comparable molecular masses. Consequently,more energy is required to overcome these forces,leading to higher boiling points for aldehydes and ketones compared to hydrocarbons and ethers. Thus,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

Assertion : The boiling points of aldehydes and ketones are higher than hydrocarbons and ethers of comparable molecular masses.
Reason : There is a weak molecular association in aldehydes and ketones arising out of the dipole-dipole interactions.
