    The compound \[C{{H}_{3}}-O-{{C}_{3}}{{H}_{7}}\] and \[{{C}_{2}}{{H}_{5}}-O-{{C}_{5}}{{H}_{5}}\] exhibit:

    A) Optical isomerism

    B) Cis-trans isomerism

    C) Metamerism      

    D) Chain isomerism

    Correct Answer: C

    Solution :

    [c] Metamerism Metamerism: Compounds having same molecular formula but different number of carbon atoms on either side of the functional group are called Metamerism and the phenomenon is called Metamerism. \[C{{H}_{3}}-O-{{C}_{3}}{{H}_{7}}{{C}_{2}}{{H}_{5}}-O-{{C}_{2}}{{H}_{5}}\] \[\underset{1-\,methoxypropane}{\mathop{C{{H}_{3}}-O-C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}}}\,\,\,\underset{ethoxyethne}{\mathop{\,\,C{{H}_{3}}C{{H}_{2}}-O-C{{H}_{2}}C{{H}_{3}}}}\,\]
