I was wondering what's your opinion about the ability of molecules containing polar atoms to form van-der-Waals interactions.
For example piperazine. Each carbon atom is connected to a heteroatom (N), causing partial dipoles. Can it then form attractive van-der-Waals interactions with, for example, a phenyl ring (given a favourable distance)?
To my knowledge, the methyl part of a methoxy group can, at least according to literature.
Any help is greatly appreciated! Thanks
