I'm having trouble with WHY
hexane makes a good recrystallizing solvent for trans-stilbene.
I've already completed the experiment, so I know that it does work. Trans-stilbene will recrystallize in hexane. However, I was told by my instructor to use this solvent. It probably would've been my last choice because I know that in choosing a solvent you should pick one that differs slightly in polarity.
Going with the saying 'like dissolves like,' isn't trans-stilbene nonpolar? Hexane is nonpolar, so why would trans-stilbene be only slightly soluble in hexane at room temperature and not fully soluble? I have a feeling that it either has something to do with the molecular weight or the aromatic rings, but I'm not sure. Any help would be greatly appreciated!
