Most Alkyl Halides Are Nonpolar Covalent Compounds And,therefore,are Soluble in Nonpolar

Most alkyl halides are nonpolar covalent compounds and,therefore,are soluble in nonpolar solvents and insoluble in water.Cycloheptatrienyl bromide is an unusual alkyl halide in that it is insoluble in nonpolar solvents,but is readily soluble in water! This behavior is consistent with cycloheptatrienyl bromide being an ionic compound.Why does cycloheptatrienyl bromide exist as an ionic compound? Explain by comparing the covalent structure to the ionic structure.
