Question

When the mixture of biodiesel and glycerol is in separatory funnel, glycerol appears denser than biodiesel. What can be the chemical reasoning of the observation?

Answer 1

as we can see from structure of glycerol that it have 3 -OH sites available for H bonding which give rise to very high intermolecular forces between molecules

Allhongh glyeral is a # Palar malecule with hugh But it is Comp ound Palarity 2 high ablity to rm ndng St SA- As CH2 is extensvely Jused CH a M ond t И CM2 hawe 3 Mtes Hbondng

And properties like viscosity boiling point and density depends upon intermolecular forces due to high intermolecular forces it have high density than biodiesel as it have only week vanderwall forces so less intermolecular forces give rise to less density.
