    A)  propane             

    B)  pentane

    C)  150-pentane                    

    D)  neo-pentane

    Correct Answer: D

                     Neo pentane\[C{{H}_{3}}-\underset{C{{H}_{3}}}{\overset{C{{H}_{3}}}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{3}}\]contains all hydrogen atoms equivalent, so it will give only one monochord derivative on halogenation.
