Problem: Based on the expected intermolecular forces, which halogen has the lowest boiling point? based on the expected intermolecular forces, which halogen has the lowest boiling point? I2 F2Cl2Br2

FREE Expert Solution

We’re being asked to determine which halogen has the lowest boiling point


Recall that there are several types of intermolecular forces:

1. Ion-dipole interaction – occurs between an ion and a polar covalent compound

2. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F

3. Dipole-dipole interaction – occurs between two polar covalent compounds

4. Induced-dipole interaction – occurs when a nonpolar compound interacts with a polar compound

5. Dispersion forces – occurs in all compounds. This is the primary intermolecular force exhibited by nonpolar compounds.
