    Which type of isomerism is shown by propanal and propanone?

    A)  Functional group            

    B)         Metamerism

    C)         Tautomerism                   

    D)         Chain isomerism

    Correct Answer: A

    Solution :

    When two compounds have similar molecular formula but differ in the functional group then the isomerism is called functional group Isomerism\[i.e.,\]                 \[C{{H}_{3}}C{{H}_{2}}CHO\]and\[C{{H}_{3}}\overset{\begin{smallmatrix}  O \\  |\,\,| \end{smallmatrix}}{\mathop{C}}\,C{{H}_{3}}\]
