Question

1. Draw the bond-line structure for structure for (2S,3R)-3-deutero-2-ethyloxirane . 2. Using bond-line structures, draw the reaction that would give this epoxide using meta-chloroperoxybenzoic acid (mCPBA). Name the alkene starting reagent 3. Draw the product from acid catalyzed ring opening of the epoxide using methanol andcatalytic sulfuric acid. Name the product . 4. Draw the product from base catalyzed ring opening of the epoxide using sodiummethanethiolate (NaSCH3). 5. Draw the acid catalyzed mechanism for ring opening of the epoxide. Show all lone pairs andformal charges on all intermediates and which steps are equilibrium steps and which step arenot equilibrium steps. Identify which step is rate limiting. 6. Draw the rate law for acid catalyzed reaction. I have steps 1-5 but how do you figure out the rate law?

Explanation / Answer

identify the rate determining step of the acid catalyzed reaction.. and then rate law is equal to reactants of the rate determining step.
