Question

Glycerol (HOCH2CHOHCH2OH) is used in cosmetics. Do you expect its viscosity to be larger or smaller than the viscosity of ethanol, CH3CH2OH? Why or why not?

Answer 1

Thank for some points you should ask your people for some help

Answer 2

Glycerol is predicted to have a higher viscosity. Glycerol is a larger molecule with more instances of hydrogen bonding that lead to stronger intermolecular forces between molecules compared to ethanol.
