WebCycloheptatrienyl 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. WebA polymer including a self-immolative polymer segment and a thermally-activated trigger moiety is described. The self-immolative polymer segment includes a head end, a tail end, and a plurality of repeating units. The trigger moiety includes a cycloaddition adduct that is covalently coupled to the head end of the self-immolative polymer segment.

This makes it aromatic. The cycloheptatrienyl anion has 8 electrons in its pi system. This makes it antiaromatic and highly unstable. The cycloheptatrienyl (tropylium) cation is aromatic because it also has 6 electronics in its pi system.
