Q.

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.

In the light of the above statements, choose the most appropriate answer from the options given below:                [2022]
1 Both statement-I and statement-II are correct.  
2 Both statement-I and statement-II are incorrect.
