    Select the best statement for the situation below

    A) This mixture given an optical rotation of zero

    B) (A) will rotate plane polarised light in clockwise direction

    C) (B)  will  rotate  plane  polarised  light  in anti-clockwise direction  

    D) None of the above statement is true

    Correct Answer: D

    Solution :

    (A) and (B) are enantiomers, hence the solution will have some net optical rotation. The direction of rotation of plane polarised light cannot be predicted by structural formula. Hence, all a, b and c statements are wrong.
