The phenomenon of profound carbocation rearrangements is an inescapable hallmark of the mechanism. W — Haloalkanes and Haloarenes Chemistry Question

💡 Solution & Explanation

A) True. Rearrangements are thermodynamically driven; molecules roll downhill in energy, migrating strictly toward more stable intermediate states. B) True. Relieving severe geometric angle strain (Baeyer strain) is a massive thermodynamic driver for ring expansion. C) True. Hydrides are exceptionally small and lightly bound, allowing them to shift across the adjacent bond with a vastly lower kinetic activation barrier compared to a massive, bulky methyl group. D) False. By definition, classic carbocation rearrangements (like 1,2-shifts) are strictly intramolecular phenomena, occurring entirely within the confines of the single vibrating molecule.
