Question

Glycerol is more viscous than propanol. Why?

Answer 1

Answer:

stronger the intermolecular force ,MRE will be the viscosity,the glycerol has more stronger intermolecular force than propanol that's why it is more viscous tha propanol

Answer 2

Answer:

The Glycerol is more viscous than propanol:

The viscosity of a liquid depends on the Strength of the intermolecular firces.Stronger the intermolecular force, the more is the viscosity of the liquid

Glycerol has three O-H groups per molecule,while water has only one O-H group per molecule. Hence, both glycerol and water can form strong intermolecular Hydrogen bonds, but Glycerol cab form more Hydrogen bonds per molecule than water.The higher extent of Hydrogen bonding in Glycerol thus makes Glycerol more viscous than water.
