Okay, I remember from AS that we used either CCl4 or hexane to separate the two layers in the identification of the halogen in the halogenoalkane (the reaction of silver nitrate with ethanol and the halogenoalkane, producing precipitates of AgCl, AgBr or AgI). And for the recrystallisation of methyl-3-nitrobenzene, we dissolve it in hot ethanol. The point is, when do I use ethanol, hexane or CCl4 as a solvent for organic compounds? And which particular organic compounds dissolve in which?
Hexane is non-polar and dissolves non-polar substances.
DCM is more prevalent.
