Arrange in increasing order of boiling point and give reason? Benzaldehyde, p-tolualdehyde, p-nitrobenzaldehyde, acetophenone.

I know that acetophenone has the least boiling point because the methyl group on carbonyl carbon, decreases its electrophilicity due to +I effect.
How do I compare other para-substituted benzaldehydes?
I know that nitro group is electron withdrawing while methyl is electron releasing. Also meta- positions in benzaldehyde is electron deficient because of resonance (-CHO group pulls electrons from the benzene ring, thus deactivating it.)

Do you think you could quote the normal boiling points?

Explanation:

The scientist interrogates data...and there are no data included with the question. Clearly, the molecule with the greatest intermolecular force will exhibit the highest boiling point.
