Sketch the molecular orbital energy level diagrams for BrCl and deduce its ground-state electron configurations. : Univ. Interhalogen compounds are found in a vapour state, in a solid-state or in a liquid state. There are also a few other substances that are gases. ; Iodine monochloride (ICl) exists as red transparent crystals that melt at 27.2 °C to form a choking brownish liquid (similar in appearance and weight to bromine). Dissolved elemental mercury, Hg(0), is also widely observed in sediments and water.

Find the number of electron pairs, number of lone pairs, electronic geometry, molecular geometry, and Lewis structure for {eq}BrCl_5 {/eq}. They do not contain hydrogen atoms. There are three major types of intermolecular forces: London dispersion force , dipole-dipole interaction, and ion-dipole interaction. The strength or weakness of intermolecular forces determines the state of matter of a substance (e.g., solid, liquid, gas) and some of the chemical properties (e.g., melting point, structure). For example, chlorine monofluoride is a gas.
