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).

Other Answer Choices:

molecules

boiling

energy

separate

between

gas

higher

bonds between __________  do not break ; 

forces between ______________  (intermolecular forces) are overcome 

bonds between atoms are ___________  

forces between molecules are _________ ;
