Recall: Viscosity is the resistance of a fluid to flow. Generally, viscosity increases with:
– decreasing temperature
– increasing molar mass
– stronger intermolecular forces
Neopentane and n-pentane are isomers, compounds with the same molecular formula but different structure. They both have the same molecular formula, C5H12. This means we can ignore their molar mass when comparing viscosity.
Compare the viscosity of neopentane, (CH3)4C, and n-pentane.
