WebGlycerol has three OH - groups that are able to undergo hydrogen bonding, compared to water which only has one OH-group that can form hydrogen bonding. Therefore, we can say that glycerol has a higher viscosity, and also a stronger intermolecular force. Fig. 3: The structures of glycerol and water, Isadora Santos - StudySmarter Originals. WebGlycerol. Glycerol is propane which has three -OH groups added, so making it a triol (its correct name is actually 1,2,3-propanetriol ). These produce a great deal of intermolecular hydrogen bonding, and as a result glycerol is a viscous, syrupy liquid. Because of this, it is often used in cosmetics, pharmaceuticals and food.

WebIn organic compound terms the difference between ethanol and glycerol. is that ethanol is a simple aliphatic alcohol formally derived from ethane by replacing one hydrogen atom with a hydroxyl group: CH 3 -CH 2 -OH while glycerol is 1,2,3-trihydroxy-propane or propan-1,2,3-triol; a trihydric alcohol.
