Synthesis of hexane-3,4-diol from fran-3-hexene may be accomplished in two ways:
(i) `OsO_(4)` hydroxylation and
(ii) Epoxide formation by reaction of alkene with `PhCO_(3)H` followed by basic hydrolysis.
Which of the following statements about the products from these reactions is correct?

Options

A. The two methods give the same product.
B. (i) gives chiral isomers , (ii) gives an achiral isomer.
C. (i) gives an achiral isomer, (ii) gives chiral isomers.
D. Two different isomers are formed, but both are chiral.

Answer

B

Explanation

Trans + `underset("cis addition")(OsO_(4)overset(HOH)(to))"Racemic or threo"`
Trans `underset("trans addition")(+PhCO_(3)Hoverset(HOH)(to)) "Meso or erythro"`
