    In \[\text{LiAl}{{\text{H}}_{\text{4}}}\text{,}\]the ligand is

    A)  H                           

    B)         \[{{\text{H}}^{\text{+}}}\]

    C)  \[{{\text{H}}^{-}}\]                        

    D)         \[2{{H}_{2}}\]

    Correct Answer: C

    Solution :

    \[\text{LiAl}{{\text{H}}_{\text{4}}}\]is actually \[\text{Li }\!\![\!\!\text{ Al(}{{\text{H}}_{\text{4}}}\text{) }\!\!]\!\!\text{ }\text{.}\]In it, the ligand present is hydride ion, i.e., \[{{\text{H}}^{-}}.\]
