    The compound exhibiting maximum value of equivalent conductance in a fused state is

    A)  \[SrC{{l}_{2}}\]                                

    B)  \[CaC{{l}_{2}}\]

    C)  \[MgC{{l}_{2}}\]                             

    D)  \[BeC{{l}_{2}}\]

    Correct Answer: A

    Solution :

                     On moving downward in a group, atomic size increases, and hence, covalent character decreases. Thus, \[SrC{{l}_{2}}\] is most ionic among the given compound ie, it will give ion readily when is in fused state. Hence, \[SrC{{l}_{2}}\] exhibit the maximum value of equivalent  conductance in fused state.
