Identify the chiral center in the product from this experiment. Is the product optically active? Explain your answer.
Question 2
Examine the mechanism and the intermediates in the reaction to explain why the thiamine-catalyzed synthesis of benzoin is sensitive to electron-withdrawing and electron-donating substituents in the four position (the para position) of the benzene ring of the aldehyde. For each of the steps in the mechanism, indicate whether electrondonating or electron-withdrawing substituents stabilize the intermediate.
