Compare the boiling points of 1-pentyne and 1-octyne. compare the vapor pressure curves of 1-butene and 1-heptene.

Did your answers include all of the following?

1-pentyne has a lower boiling point than 1-octyne.  

1-butene has higher vapor pressures at lower temperatures than 1-heptene.

The differences in boiling points and vapor pressures result from differences in the chain lengths of the molecules.

Larger molecules have stronger intermolecular forces of attraction than smaller molecules.

More energy is required to move larger molecules into the vapor phase from the liquid state.
