Final answer:
Long chain hydrocarbons are cylindrical with higher boiling points and viscosity, while short chain hydrocarbons are spherical with lower boiling points and viscosity.
Step-by-step explanation:
Properties of Long Chain Hydrocarbons:
- Long and cylindrical shape
- Higher boiling points
- Higher viscosity
- Greater surface area for intermolecular forces
Properties of Short Chain Hydrocarbons:
- Branching makes them spherical in shape
- Lower boiling points
- Lower viscosity
- Less surface area for intermolecular forces
