Question

B Mechanisms Complete the proposed mechanisms on the following pages by adding arrows or drawing products as indicated Complete the table below for each possible mechanism given. Label each type of mechanism as syn, anti or mix of syn and anti addition and label the expected products as of each mechanism as "meso, "racemic mix. or mix of meso and racemic" products Note: Are all of the proposed mechanisms acceptable arrow pushing mechanisms? Can any proposed mechanisms be eliminated prior to experimentation? Hint: there is one mechanism with bad arrow pushing. Indicate the incorrect mechanism on the table by brief note in the mechanism 9 points per row Mechanism Addition (syn, anti or Products (Meso compound Reaction or racemic mix or all mix of syn an Permanganate Oxone A Woodward

Answer 1

Just all are forming 1,2-diols. This type of reactions are very common in carbohydrate chemistry. In all of three cases either abstracting proton (H+) or losing proton we have observed. Do not panic with bigger structures. Even a space shuttle can be operated with a small ignition key.
