Question

Propylene oxide (2-methyloxirane or 1,2-epoxypropane) can be converted to 1,2-propanediol by the 7. action of either dilute acid or base in water. When optically active (R)-(+)-propylene oxide is used, the 1,2-propanediol obtained from the acid hydrolysis (HsO) has an optical rotation opposite from the alkaline hydrolysis (OH, H20). Write the stepwise mechanism of each hydrolysis that is likely to explain these facts. Use curved arrows to show the flow of electrons. Enantiomers OH Он opposite optical rotation Н,о но.
