    Which of the following compounds exhibit functional isomerism?

    A)  \[{{C}_{6}}{{H}_{6}}\]                   

    B)  \[{{C}_{3}}{{H}_{6}}O\]

    C)  \[{{C}_{2}}{{H}_{5}}Cl\]               

    D)  \[{{C}_{5}}{{H}_{12}}\]

    Correct Answer: B

    Solution :

                     Compounds having same molecular formula but differ in the nature of functional groups are functional isomers. In these compounds \[{{C}_{3}}{{H}_{6}}O\]shows functional isomerism because the possible structures of \[{{C}_{3}}{{H}_{6}}\]are: \[C{{H}_{3}}C{{H}_{2}}CHO\](Propionaldehyde)and \[C{{H}_{3}}-\underset{O}{\mathop{\underset{|\,|}{\mathop{C}}\,}}\,-C{{H}_{3}}\](Propanone) These are the functional isomers.
