Question

6 ( 30 Points) Draw a pushing mechanism for H₂O complete the following arrow reaction. он + HBC

Answer 1

As in this reaction rearrange product group enters not an position of a Br, the leaving group) is obtained therefore this reaction occur by rearrangement of carbocation intermidiate. ne this reaction occuro via SNI mechanism in DR . Meo X + HBV A Mechma 1,2-shifting of -CH3 group Bro. GBY Sub9carbocations less stable) Dronen 3 – carbocation more stable) In the 1st step deperture of leaving group Bye occur to form 2 - carbocation which is less stable. The shifting - CH₂ group leads to the formation of stable 3 - carbocation, which then attack by the nucleophile Ho to form corresponding 3 - alcohol. as major product. In the last step übarated he and in the 1st step barated Bre, combines to form HBY. 19. Na N atale
