Why acetaldehyde has a higher boiling point than ethylamine?
Ethylamine has 2 hydrogen bonds, Acethaldehyde has no one, so why the second has a higher boiling point?

Is hydrogen bonding the only intermolecular force of consequence in this situation?
How effectively can ethylamine hydrogen bond with itself? It has a lone pair on the nitrogen to serve as an H-bond acceptor, and has two amine hydrogens that can be donated. How large of a difference is there between the two boiling points? |

The boiling points are very close:
Acetaldehyde 68ºF Ethylamine: 62ºF |
