Why does iodine have a higher boiling point than chlorine?
Question: Why does iodine have a higher boiling point than chlorine?
Iodine has a higher boiling point than chlorine because of its larger atomic size and greater number of electrons. Iodine atoms are larger and have more electrons than chlorine atoms, resulting in stronger London dispersion forces between the molecules. These forces require more energy to overcome, leading to a higher boiling point for iodine compared to chlorine. Additionally, iodine molecules are held together by covalent bonds, which are stronger than the weaker intermolecular forces present in chlorine molecules.
