    A)  \[{{C}_{2}}{{H}_{6}}\]

    B)  \[{{C}_{2}}{{H}_{4}}\]

    C)  \[C{{H}_{4}}\]

    D)  All of these diffuse at equal rate

    Correct Answer: A

    Solution :

                    According to Grahams law,\[r\propto 1/\sqrt{M}\] Hence, \[{{C}_{2}}{{H}_{6}}\] is slowest diffusing due to highest molecular weight among the given hydrocarbons.
