Help with ALL #1-6 carbocations

1. Epoxides under acidification yield carbocations. On the basis of carbocation stability, which pathway is major? pathway 1 pathway 2 2. Alcohols under acidification yield carbocations. Provide curly arrows, and intermediate and final carbocation structures. a. b. c. 3. Select which structure is an especially stable allylic carbocation. Select which structure is an especially unstable vinylic carbocation. 4. Present the ' 123 ' labeling system to determine which double bond is positioned for allylic resonance. Draw the resulting resonance structure from the correctly positioned curty arrow. Remember conservation of charge and conservation of the number of carbon atoms. 5. Carbonyls, like this ketone, under acidification yield carbocations. Provide curly arrows. 6. Di-ols (diols) under acidification can yield a carbocation intermediate followed by a carbonyl. Provide curly arrows
