Question

Please helpAnswer the following three questions using the reaction scheme that is shown below.
7) Provide the missing chemicals in the reaction sequence shown below by filling in the blocks provided
with the reagents needed to complete the reaction. Assume that for Step III only one of the
enantiomers produced in Step II is carried on in the synthesis.
Step I
Step II
Step III
CH3
Br
Step IV
8) In the reaction shown in Step IV, will the rate of the reaction increase or stay the same as the
concentration of the nucleophile increases? How do you know based on the reaction scheme? Explain.
9) In the reaction shown in Step II, what is the ratio of the two enantiomers that are formed? Explain
why it is that this particular ratio is formed. (Hint: the structure of the intermediate could prove
useful).
