Compare the vapor pressure curves of 1-butene and 1-heptene. explain your reasoning.

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.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

c. electrical charges of ionic bonds.
