- The dominant electronic character of hydrophilic macromolecules is polar / nonpolar, therefore they are soluble in polar aqueous solutions, such as blood and cytoplasm. The dominant electronic character of hydrophobic macromolecules is polar / nonpolar, therefore they do not dissolve in water but are soluble in nonpolar solutions, such as fat and cell membranes.

1st attempt M See Periodic Table Two liquids - one polar, one nonpolar - have the same molar mass. Which one has the higher boiling point? Choose one: A. The polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions. B. They will have similar boiling points, since the dispersion forces depend upon molar mass. C. The nonpolar liquid will have the higher boiling point, since its molecules are more loosely held together. D. The nonpolar...
