CHM 235 Recitation #10 Instructions: First, determine and write down the mechanism(s) expected to occur in...
9. a) Write the detailed Sn1 mechanism for the reaction of (S)-3-bromo-3-methylhexane with H20, showing curved arrows, relevant lone pairs, formal charges, stereochemistry for each step. Include any transition states and/or intermediates, and name the product(s). b) A racemic mixture results from a reaction of the chiral alkylbromide starting material below, and acetate. at hope ܬ Write the complete mechanism for the synthesis. Show the curly arrows, relevant lone pairs and all formal charges for each step. Include any transition...
s. Write out the complete mechanism, using curved arrows and all intermediate(s), of a first-order elimination of 3-chloro-3-methylpentane with sodium ethoxide in ethanol (8 points). Be sure to write out major and minor products, and indicate why each is major/minor (5 points). Indicate the name of each step, and identify which reagent is concentration-dependent, kinetically (2 points). 4. For the second-order substitution reactions below, draw the expected product(s), if any (6 points). CI NaBr OCH3 NaN3 2
