    A)  3-Ethyl-2, 2-dimethylpentane

    B)  4-Isopropyl heptane

    C)  4-Ethyl-3 methyl-4-w-propyloctane

    D)  4, 4-Diethyl-3-methyIheptane

    Correct Answer: B

    Solution :

    : \[\underset{2,2,4,4-tetramethylhexane}{\mathop{{{H}_{3}}C-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}}\,-{{H}_{2}}C-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}}\,-{{H}_{2}}C-C{{H}_{3}}}}\,\] is isomeric with 4-isopropylheptane.
