    Which of the following is not isomeric with diethyl ether?

    A)  Methyl n-propyl ether

    B)  Butan-1-ol

    C)  2-methyl propan-2-ol

    D)  Butan-2-one

    Correct Answer: D

    Solution :

                    Butan-2-one\[C{{H}_{3}}-\overset{O}{\mathop{\overset{\mathbf{||}}{\mathop{C}}\,}}\,-C{{H}_{2}}-C{{H}_{3}}({{C}_{6}}{{H}_{8}}O)\]is not isomeric with diethyl ether\[C{{H}_{3}}C{{H}_{2}}-O-C{{H}_{2}}-C{{H}_{3}}{{({{C}_{4}}{{H}_{10}}O)}_{3}},\]because both are differing in molecular formula.
