The standard heat of vaporization, AH vap of SO, is + 24.3 kJ/mol and that of F,is +5.9 k//mol.
a. Identify the types) of intermolecular forces) that exist in pure samples of each compound.
For SO2, the intermolecular forces present are likely dipole-dipole interactions and London dispersion forces. These intermolecular forces are responsible for the relatively high heat of vaporization of 24.3 kJ/mol.
For F2, the intermolecular forces present are likely only London dispersion forces. This is supported by the lower heat of vaporization of 5.9 kJ/mol compared to SO2.
