The boiling point of F2 is -188 degrees Celsius. Which of the following best predicts the boiling point of I2?
Lower than -188°C because permanent dipoles created in fluorine are stronger than temporary dipoles in iodine.
Higher than -188°C because dipole-dipole interactions in iodine are stronger than dispersion forces in fluorine.
Lower than -188°C because fluorine is more polar than iodine because of its higher electronegativity.
Higher than -188°C because dispersion forces are stronger in iodine due to a greater number of electrons.
