IMF's of Gasoline

There are weak intermolecular forces between isooctane molecules and here is how we know:

• Isooctane has a high vapor pressure meaning the molecules are not held tightly to one another.

• Isooctane molecules are held together by only london dispersion forces.

• Isooctane has a low boiling point.

• Isooctane is a liquid at room temperature

• Isooctane has no hydrogen bonding as seen in its lewis structure, it has no oxygen, nitrogen, or fluorine
