This might have something to do with the structure of caffiene but i am not sure!!!

There is a saying "Like dissolves like". Ether is a polar organic solvent and hexane is a nonpolar organic solvent. Caffeine is a somewhat polar molecule and therefore will show better solubility and by extension extractability in ether.

This all has to do with polarity. The extra polar solvents will disolve polar compounds. The least polar compounds are hydrocarbons, of which hexane is one. The extra electro-destructive atoms on the molecule, the extra polar. Electro-destructive atoms are O, S, P and others. the different attention is the ratio of the style of electro-destructive atoms to carbon atoms. Water (H2O) in basic terms has one O atom yet 0 carbons - it particularly is totally polar. a lot so as that it will not disolve in non-polar solvents like hexane. They style 2 layers. Diethyl ether is CH3CH2--O--CH2CH3. See, there is an O in there. Hexane is CH3CH2CH2CH2CH2CH3 or C6H14. No electro-destructive atom, non-polar. Caffeine is C8H10N4O2 and has various double-bonds. those additionally upload to polarity. So the final rule is "Like disolves like". Hexane may well be extra perfect at disolving and extracting parafin wax.

Look it up in the Handbook of physic and chemistry from CRC
