Amongst aldehydes and ketones, ketones have higher boiling point. This is due to the presence of two electron donating alkyl groups around the C=OC=O group which makes them more polar.
For example: the boiling point of CH3−CHOCHX3−CHO is 322 K and dipole moment is 2.52 D.
Boiling point of CH3−CO−CH3CHX3−CO−CHX3 is 329 K and dipole moment is 2.88D
Dipole moment of CH3−CO−CH3CHX3−CO−CHX3 is greater than of CH3−CHOCHX3−CHO. This because there are two electron donating CH3CHX3 groups around C=OC=O bond whereas there is only one CH3CHX3 group around C=OC=O in CH3CHOCHX3CHO.
As dipole moment is greater so it is more polar and hence has higher boiling point
