Question
Explain why HF is less viscous than H2O.
✓
Answer
There is greater intermolecular hydrogen bonding in H2O than that in HF as each H2O molecule forms four H-bonds with other water molecules, whereas HF forms only two H-bonds with other HF molecules. Greater the intermolecular H-bonding, greater is the viscosity.
Hence, HF is less viscous than H2O.
Hence, HF is less viscous than H2O.
