Order these carbocations from most stable (1) to least stable. (5) If there is resonance, that can make the carbocation more stable than if there isn't; for example, primary benzylic is more stable than primary allylic, which is more stable than secondary, as a general rule. Order these carbocations from most stable (1) to least stable. (5) If there is resonance, that can make the carbocation more stable than if there isn't; for example, primary benzylic is more stable than...
