    Which of the following compounds will show metamerism?

    A)  \[C{{H}_{3}}-CO-{{C}_{2}}{{H}_{5}}\]

    B)  \[{{C}_{2}}{{H}_{5}}-S-{{C}_{2}}{{H}_{5}}\]

    C)  \[C{{H}_{3}}-O-C{{H}_{3}}\]

    D)  \[C{{H}_{3}}-O-{{C}_{2}}{{H}_{5}}\]

    Correct Answer: B

    Solution :

     Compounds having bivalent functional group (like etc) with atleast 4  carbon atoms (in case of ether and thioether) or atleast 5 carbon atoms (in case of ketones) exhibit metamerism. Hence, \[{{C}_{2}}{{H}_{5}}-S-{{C}_{2}}{{H}_{5}}\]will show metamerism.
