Is caffeine soluble in a nonpolar solvent? why?

Homework Answers

Answer #1

Caffeine(C8H10N4O2) common name trimethylxanthene naturally produced by several plants such as coffee beans, cocoa beans, tea etc. Its an alkaloid containing nitrogen and properties of an alkali.Solubility of a substance in solvents depend upon how efficiently the solvent molecule break interactions between the solute and solvent molecule.This is of course broad generalization that water is highly polar molecule while the caffeine is partially polar molecule has a significant hydrophobic portion. In water caffeine makes hydrogen bonds invoving atoms with free electron pair (N & O) so caffiene is readily dissolve in nonpolar solvent (cholroform and other organic solvents)instead of water.

I know that 1:4 acetate; hexane eluting solvent is nonpolar. So what about the 1:2 acetate; hexane eluting solvent? Is it polar or non polar? When I used 1:4 acetate; hexane eluting solvent, I got that the starting material was more polar from the product because it has a smaller Rf value? If the eluting solvent changed from 1:4 acetate; hexane to 1:2 acetate; hexane, would the Rf values get larger? smaller? same? Explain why please

extration of caffeine. a.Magnesium sulfate is the drying agent used in this experiment. Why is it necessary to use a drying agent before removing the organic solvent on the rotary evaporator? b. Adding sodium chloride can often help cause emulsions to breakdown and separate in to distinct layers. Use the principles of solubility to explain why this works.
