1. Write the mechanism for the reaction of 1-butanol with HBr and include a brief explanation of the following points related to the mechanism. • Comment on the leaving group and briefly explain why this reaction requires acidic conditions. Explain briefly why this reaction proceeds via the SN2 mechanism, rather than the SN1 mechanism. (Hint: Explain why the direct substitution is favored. Explain why the reaction doesn't proceed via a carbocation intermediate.)
(a) For each substitution reaction, circle whether it proceeds by an Sy1 or S 2 mechanism. (1.5 pts) (b) Draw the major organic product for each reaction. Be sure to indicate the appropriate stereochemistry, where necessary (1.5 pts) 2. NaCN S1 or S 2? Br THF SN1 or Sy2? но CH3 Hас, SN1 or SN2? CH,он
