the first step. why is it br2 and COOH? shouldnt the Br add to the
starting material, not COOH? is this alpha bromination in
acid?Homework Answers

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)

In the first step of fatty acid oxidation, the fatty acid (R-COOH) is converted to its coenzyme A derivative in the following reaction: R-COOH + ATP + COA-SH -->R-CO-S-COA+AMP+PP The standard free-energy change (Delta G") for this reaction is -15 kJ/mol. Another reaction drives the reaction forward to a greater extent. This reaction is: A. Pyrophosphate is hydrolyzed to 2 phosphate molecules B. AMP is hydrolyzed to adenine C. The fatty CoA precipitates to remove it from the product side...
