The question is which stereoisomer predominates as the major product? Using scratch paper, draw the starting material and reagent, and then use what you know about reaction mechanisms to determine the correct mechanism for this reaction. Then, identify the product and the correct stereoisomer of the final product (R, S, E, or Z). Fill in the blanks below with the necessary information. a. What mechanism is controlling this reaction (SN1, SN2, E1, or E2)? b. Which stereoisomer product predominates (R, S, E, or Z)? c. What is the full name of the major product?arrow_forward
