Elemental iodine (I₂) is a solid at room temperature. What is the major attractive force that exists among different I₂molecules in the solid? A) dipole- dipole attractions B) covalent- ionic interactions C) London dispersion forces D) dipole- dipole rejections E) ionic- dipole interactions

Question

Quizplus · Accepted Answer

Elemental iodine is a nonpolar molecule, therefore, there are no dipole moments to create dipole-dipole attractions (A) or ionic-dipole interactions (E). Additionally, there are no covalent or ionic bonds present in a covalent compound such as iodine. The only attractive force between iodine molecules is London dispersion forces (C), which are caused by temporary dipoles that occur due to fluctuations in the electron cloud around the molecule.
