    Answer:

    London dispersion forces are the only type of intermolecular forces that nonpolar molecules exhibit.

    The molecules in SO2 (g) exhibit dipole-dipole intermolecular interactions.

    CH3CH2CH3 has stronger London dispersion forces than does CH4.

    Explanation:

    London forces result from temporary shifts or distortion in the electron cloud of non-polar molecules. London forces occur in all substances; whether polar or non-polar. However, it is the only kind of intermolecular force in non-polar molecules and noble gases.

    Polarity in a molecule stems from difference in electronegativity between the atoms in the molecule. SO2 is a polar molecule due to the magnitude of electronegativity difference between sulphur and oxygen. Hence SO2  exhibit dipole-dipole intermolecular interactions since it is a polar molecule.

    The magnitude of London dispersion forces depends on the molar mass and surface area of molecules. CH3CH2CH3  has a higher molar mass and larger surface area than CH4 hence CH3CH2CH3  has stronger London dispersion forces than does CH4.
