Carbocations can undergo rearrangements to form more stable carbocations. A fourmembered ring can expand to a five-membered ring and a five-membered ring can expand to a six-membered ring, but a six-membered ring will not expand to a seven-membered ring. Provide an explanation for why the expansion of four- and five-membered rings is favorable, but the expansion of six-membered rings is not. O ** Carrow_forward1.
