answer all questions 1. For the following substrates, predict whether a carbocation rearrangement will take place in an SN1/E1 mechanism by first drawing the carbocation intermediate, then deciding if the carbocation will rearrange (can it form a more stable carbocation by hydride or methyl shift?): Carbocation: Sturcture Rearrange? If yes, draw the rearranged product. If no, write No н.с Br Н,с, Cн, 2. For each pair of nucle ophiles, circle which will react faster with CHsl in an Sx2 reaction....
