In step I the alpha bromination of ketones is acid catalyzed.
1. In step I the alpha bromination of ketones is acid catalyzed. a. What acid is formed as Step 1 progresses? b. Why are alpha bromination reactions acid catalyzed? 2. Substitution of bromine by t-butyl amine is the second step of the reaction today. Secondary alkyl halides can undergo substitution by Sn1 or Sn2 mechanisms. Explain (in terms of electronic interactions) why an Sn2 mechanism is favored when the halogen is alpha to a carbonyl. (Hint: Like charges on adjacent atoms are unfavorable)

OH 1-Butyne Acetaldehyde Alkyne anions react with the carbonyl groups of aldehydes and ketones to form alkyayl alcohols. The reaction mechanism between 1-butyne and acetaldehyde includes the following steps: 1. Sodium amide deprotonates the terminal alkyne 2. The alkyne anion acts as a nucleophile and adds to the aldehyde carbonyl: 3. Proton transfer from solvent forms the product alcohol. Diagram the mechanism on a separate sheet of paper, and then draw the structure of the product(s) of step 2. ....
