Question

Why is boiling point of aldehyde and ketone higher than hydrocarbons?

Answer 1

The boiling point of aldehyde and ketone higher than hydrocarbons due to hydrogen bonding .

 

Answer 2

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.
