Supercritical carbon dioxide is used as a non polar solvent to extract caffeine from coffee beens. Supercritical gases are not quite gases and not quite liquids but sort of in between.
The nonpolar solute is dissolved in the nonpolar solvent.
It is nonpolar
Yes, like dissolves like so a nonpolar solvent dissolves nonpolar solutes and polar solvents dissolve polar solutes
Nonpolar solvent
It depends on the polarity of the solute and the solvent. If the solute is polar, then it will only dissolve in a polar solvent If the solute in nonpolar, then it will only dissolve in a nonpolar solvent
Molecules with many polar bonds are soluble in polar solvents.Also, molecules with none or few polar bonds (many non-polar bonds) are soluble in non-polar solvent. e.g Water is a polar solvent so substances with many polar bonds are soluble in it.
nonpolar solvents
Bromine is nonpolar and needs a nonpolar solvent to do the bromination reaction. CCl4 is a heavy, nonpolar solvent that dissolves the heavy Br2 molecule. With lighter nonpolar solvents such as hexane, the high density Bromine settles out.
Water
For nonpolar substances, anything that is symmetrical is nonpolar, so something likeHexane (C6H12) or any other hydrocarbon would work.
This is because the nonpolar pigments would just simply dissolve in the nonpolar solvent instead of traveling up the TLC plate.
a nonpolar solvent will dissolve a nonpolar solute
