Alkanes and Alkenes: Physical Properties by Mind Map: Alkanes and Alkenes: Physical Properties

1. Physical States:

1.1. 1-4 Carbon Atoms = Gas

1.2. 5-14 Carbon Atoms = Liquid

1.2.1. This is because of the greater Van der Waals forces that exist between molecules in alkenes and alkanes with more carbon atoms.

1.3. 15+ Carbon Atoms = Solid

2. Solubility in water

2.1. Alkanes and Alkenes are insoluble in water, but are soluble in non-polar solvents instead.

3. Melting points / Boiling points

3.1. As the number of carbon atoms increase,so does the melting and boiling point of the alkane/alkene this is also a result of the increased Van der Waals forces between molecules.

4. Conductivity

4.1. Alkanes and Alkenes do not conduct heat or electricity well.
