1.	Which of the following is true for the given reaction? `overset( :overset(..)O:^-)overset(\|)((S)-C_2H_5CHCH_3+CH_3I)rarroverset(OCH_3)overset(\|)C_2H_5CHCH_3+I^(-)`A. The configuration is unchanged and the product is `S`B. The configuration is chnaged and the product is `R`C. The configuration is chnaged and product is `S`D. The configuration is unchanged and the product is `R`
Answer» Correct Answer - A Because the bonds to the chiral carbon atom are not distrubed, the configuration is unchanged. Since the priority order is unchanged, the product is `(S)`. Note that product (like reactant) is optically active. The products and reactants will have different specific rotations and their signs may differ. specific rotations of reactants and products are independent of each other.
