Boiling point
Explanation
As the size of hydrocarbon molecules increases, the boiling point also increases due to greater van der Waals forces.
Common mistake
Misunderstanding Hydrocarbon Properties
Students often think that all hydrocarbons have the same boiling point, viscosity, and flammability regardless of their molecular size.
Emphasize that the properties of hydrocarbons, such as boiling point, viscosity, and flammability, change with the size of their molecules. Larger molecules generally have higher boiling points and viscosities.
