    Lithium aluminium hydride reacts with silicon tetrachloride to form. [JEE Online 15-04-2018 (II)]

    A) \[LiCl,Al{{H}_{3}}\] and\[Si{{H}_{4}}\]

    B) \[LiCl,AlC{{l}_{3}}\] and \[Si{{H}_{4}}\]

    C) \[LiH,AlC{{l}_{3}}\] and \[SiC{{l}_{2}}\]

    D) \[LiH,Al{{H}_{3}}\] and\[Si{{H}_{4}}\]

    Correct Answer: A

    Solution :

    Lithium aluminium hydride reacts with silicon tetrachloride to form LiCl (lithium chloride), \[AlC{{l}_{3}}\] (aluminum trichloride) and \[Si{{H}_{4}}\] (silicon hydride). \[SiC{{l}_{4}}+LiAl{{H}_{4}}\to LiCl+AlC{{l}_{3}}+Si{{H}_{4}}\]
