5. Answer ALL parts. (a) The reaction of cis-stilbene oxide with aqueous acid below, produces two stereoisomeric diols via an Sy2-like ring opening. но н H.H,0 H OH HO H H OH () What is the stereochemical relationship between the two diol products? (2 marks) (i) Draw a mechanism for the reaction, clearly showing the formation the two alternative diols. (6 marks) (i) The reaction of racemic trans-stilbene oxide (below) with dilute acid, produces only one diol. Draw the product, clearly indicating the stereochemistry, and draw the mechanism and explain why only one diol is formed. OH H.H20 OH (4 marks)
