draw the most stable carbocation that could be formed through a 1,2- shift from the Carbocation shown below
6. Which of the four carbocations shown is the most stable (will not rearrange) and which one(s) will undergo carbocation rearrangement(s)? Indicate the correct structures of the products of the carbocation rearrangements. To practice for the exam: use resonance structures to explain why you selected specific a carbocation as the most stable. Where applicable, use the curved arrow(s) to clearly draw the mechanism of the carbocation rearrangement. HO HO A. carbocation B is most stable and will not rearrange, and...
