Answer:
a) Higher than −34 °C because dispersion forces are stronger in iodine due to a greater number of electrons.
Explanation:
Both chlorine and Iodine are halogens. They belong to the 7th group on the periodic table.
To examine the trend of boiling point in this group we must consider the nature of the intermolecular bonds that would be formed by the molecules of these elements. We know that London dispersion forces, a type of van der Waals attraction would be more prevalent. This is so because the molecules here would be non-polar and the uneven distribution of the constantly moving electrons would initiate the intermolecular bonding.
The uneven charge distribution leads to the formation of a temporary dipole.
This makes boiling point increase down the group because more electrons becomes involved and the bond becomes stronger.
