why would dry cleaners use nonpolar tetrachloroethylene, c2cl4, to get cheeseburger grease out of clothes?
Sergeeva-Olga [200]
Grease is nonpolar. It is made up of lengthy hydrocarbon chains attached to glycerol (triacylglycerols). Because of this property, nonpolar solvents, such as tetrachloroethylene, can get grease out of clothes. This solvent acts by dissolving the grease, thereby removing it from clothes without leaving any residue.
