11.3 (ü) London dispersion forces, the only intermolecular forces between nonpolar Fmolecules. ... Glycerol has three times as many O-H groups and many more H-bonding interactions than 1-propanol, so it experiences stronger intermolecular forces and greater viscosity.

Does glycerol have dispersion forces?

The normal boiling point of triacetin is b.p = 259 ∘C , substantially lower than glycerol, even though glycerol has LESS dispersion forces in that it is a smaller molecule. Hydrogen bonding WINS as an intermolecular force.

What type of intermolecular forces does glycerol have?

(i) Glycerol: Predominant intermolecular force = Hydrogen bonding.
