Compounds that are insoluble in Organic Solvents?
« on: November 18, 2014, 06:07:09 PM »
So we are trying to find an unknown in chemistry lab, and we did the solubility tests on it. It turns out that the solid is insoluble in toluene, cyclohexane, ethanol, and acetone. The solid is soluble in water, NaOH, HCl, and HNO3. I found that ethanol and acetone are polar, while cyclohexane and toluene are nonpolar.. Not sure if the polarity matters at this point, so what types of compounds are insoluble in organic solvents?

With your experimental data, there should be a very strong conclusion.  Can you take a stab at what that might be?
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

My stab is that it is a sugar, and is polar due to the fact that it dissolved in NaOH, HNO3, H2O, and HCl...

Why do you assume unknown is organic?
