ISSUE:

Boiling points of Methylpiperidines 14 years 7 months before #93

4-Methylpiperidine has a P.eb=129°C, higher than N-Methylpiperidine P.eb=106°C. Explain why.

I have no idea, it occurs to me because of the polarity, but I don't expect more comments

According to the data, when methyl is above nitrogen the boiling point decreases more than 20ºC. We can ask ourselves, what kind of interactions between molecules are responsible for such high boiling points? And why does N-methylpiperidine have fewer interactions than 4-methylpiperidine?

N-methylpiperidine has a lower boiling point than 4-methylpiperidine, since it cannot form hydrogen bonds.
