Three key properties of hydrocarbons
Boiling point, viscosity, flammability
Boiling point definition
Boiling point definition
Temperature at which a liquid changes to gas
Long-chain hydrocarbon intermolecular forces
Long-chain hydrocarbon intermolecular forces
Strong intermolecular forces
Long-chain hydrocarbon boiling points
Long-chain hydrocarbon boiling points
Higher boiling points
Short-chain hydrocarbon intermolecular forces
Short-chain hydrocarbon intermolecular forces
Weaker intermolecular forces
Short-chain hydrocarbon boiling points
Short-chain hydrocarbon boiling points
Lower boiling points
Ethane () boiling point
Ethane () boiling point
Heptane () boiling point
Heptane () boiling point
Viscosity definition
Viscosity definition
Liquid's resistance to flow or thickness
Larger hydrocarbon viscosity
Larger hydrocarbon viscosity
Higher viscosity, thicker, flow less easily
Flammability definition
Flammability definition
How easily a hydrocarbon can combust
Smaller hydrocarbon flammability
Smaller hydrocarbon flammability
More flammable, effective fuels
Larger hydrocarbon flammability
Larger hydrocarbon flammability
Less flammable
