Amongst aldehydes and ketones  , ketones have higher boiling point ....this This is due to the presence of two electron donating alkyl groups around the C=O$\ce{C=O}$ group which makes them more polar.

for ex-For example: the boiling point of CH3-CHO =$\ce{CH3-CHO}$ is 322 K and and dipole moment is 2.52 D.

boilingBoiling point of CH3-CO-CH3 =$\ce{CH3-CO-CH3}$ is 329 K and and dipole moment is 2.88D

dipoleDipole moment of CH3-CO-CH3$\ce{CH3-CO-CH3}$ is moregreater than CH3-CHOof ..$\ce{CH3-CHO}$.this This because there are two electron donating CH3$\ce{CH3}$ groups around C=O$\ce{C=O}$ bond where aswhereas there is only 1 CH3one $\ce{CH3}$ group around C=O$\ce{C=O}$ in CH3CHO$\ce{CH3CHO}$.

asAs dipole moment is moregreater so it is more polar and hence has higher boiling point.

Amongst aldehydes and ketones, ketones have higher boiling point. This is due to the presence of two electron donating alkyl groups around the $\ce{C=O}$ group which makes them more polar.

For example: the boiling point of $\ce{CH3-CHO}$ is 322 K and dipole moment is 2.52 D.

Boiling point of $\ce{CH3-CO-CH3}$ is 329 K and dipole moment is 2.88D

Dipole moment of $\ce{CH3-CO-CH3}$ is greater than of $\ce{CH3-CHO}$. This because there are two electron donating $\ce{CH3}$ groups around $\ce{C=O}$ bond whereas there is only one $\ce{CH3}$ group around $\ce{C=O}$ in $\ce{CH3CHO}$.

As dipole moment is greater so it is more polar and hence has higher boiling point.
