Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Given below are two statements:
Statement : 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 : The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of -bonding.
In the light of the above statements, choose the most appropriate answer from the options given below :

Options:
Answer:
Solution:
The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses. It is due to weak molecular association in aldehydes and ketones arising out of the dipole-dipole interactions. Also, their boiling points are lower than those of alcohols of similar molecular masses due to absence of intermolecular hydrogen bonding.
