1.

Describe the relationship shown by the graph and use ideas about forces between molecules to explain this relationship.

The more carbons the higher the point

The carbons the larger the molecules.

larger molecules have boiling points

Larger molecules have larger forces them

The larger the forces between the molecules the more is required for them to break out of a liquid and become a

the more energy needed to the molecules, the higher the boiling point of the hydrocarbon

the larger / more the forces between the the higher the boiling point

(The key idea is that we are overcoming the intermolecular forces not breaking the strong covalent bonds so the values are low and the first 3 are gasses at room temperature).
