1. Rank the following carbocations in order from most stable (1) to least stable (4). o ó no 8 2. Consider the following carbocation. Would this carbocation undergo a rearrangement? If so, show the mechanism (curved arrows) for the rearrangement (including the rearranged cation that is the product of your curved arrows) and explain why it happens. If not, explain why it would not rearrange.
Question 9 (2 points) Which of the following carbocations is (are) likely to undergo rearrangement through a methyl shift? HC CH HC CH H₃C. CH INI a) both I and II b) both II and III OI d) 1 Question 10 (2 points) Choose a major product for the reaction below 0 Cl/AICI OCH, CI OCH OCH OCH a) I, II and Ill b) d)
Which of the following carbocation(s) cannot undergo a methyl shift or a hydride shift to be more stable than it was? Select one or more: a. Carbocation b b. Carbocationc c.Carbocation a d. Carbocation d
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...

For each of the following pairs of organic molecules, circle the one that would react with a given nucleophile at a faster rate in the Sw1 reaction, and briefly explain your choice. нссн, vs. H₂C CH₂ CH Hoc tots vs. Ho C^ots 6. Each of the following carbocations can undergo a rearrangement to give a more stable carbocation. In each case, draw the structure of the rearranged carbocation, and show the mechanism of the 1,2 hydride shift or 1,2-alkyl shift...
east stable most stable The following are three examples of the relative stability of carbocations in your answer to question 2. Each of these reactions should show a relatively stable carbocation intermediate. (a) The two-step reaction of 1-methylcyclohexene with HBr follows the Markovnikov 3. rule. (b) Choose 1-butanol or tert-butyl alcohol to undergo a 3-step reaction with HBr to form the alkyl bromide. The second step is the S1 formation of a carbocation. (c) Show the one most stable resonance...
