    A racemic acid \[C{{H}_{3}}CHClCOOH\] is allowed to react with (S)-2-methylbutan-1-ol to form ester \[C{{H}_{3}}CHCl-\underset{\underset{O}{\mathop{||}}\,}{\mathop{C}}\,-OC{{H}_{2}}CH(C{{H}_{3}})C{{H}_{2}}C{{H}_{3}}\] and the reaction mixture is carefully distilled. The correct statement about the mixture distillate is:

    A) two fractions each optically active are found 

    B)  two fractions each optically inactive are found

    C) three fractions all optically active are found  

    D) three fractions all optically inactive are found

    Correct Answer: A

    Solution :

    Racemic mixture combine separately with S to form (R, S) and (S, S), which are diastereomers.
