WitrynaIodine. The molecular lattice of iodine consists of a neat arrangement of molecules in the crystal lattice which is held together by the weak intermolecular forces. Being a non-polar molecule, the weak intermolecular bonding is due to instantaneous dipole - induced dipole interactions (the weakest of the Van der Waals forces). Witryna8 maj 2008 · Iodine chloride is polar, since chlorine has a higher electronegativity than iodine has. Is ICl polar non polar or ionic? Iodine chloride is a polar covalent molecule.

Some molecular … WitrynaIodine is more likely to dissolve in CCl 4( ). I 2(s) and CCl 4( ) are both non-polar molecular compounds, whereas water is a polar molecular compound. There are no significant attractions between the non-polar I 2 molecules and polar water molecules that would cause molecules of I 2(s) to separate. 6. Review Question (page 370)
