b.
HO-
2. CH3I
4.) Propylene oxide is a chiral molecule. Hydrolysis of propylene oxide gives propylene glycol,
another chiral molecule:
hydrolysis

H3C
HO
Provide a mechanism for the acid-catalyzed hydrolysis of pure (R)-propylene oxide (treatment
with H2SO/H20), showing the correct stereochemistry.
a.
b. Provide a mechanism for the treatment of pure (R)-propylene oxide with NaOH in water
(base-catalyzed hydrolysis), showing the correct stereochemistry.
c. Explain why acid-catalyzed hydrolysis of optically active propylene oxide gives a product with
a rotation in the opposite direction from the product of the base catalyzed hydrolysis.
