    Which one is not Lewis acid?

    A) \[Be{{F}_{2}}\]

    B) \[SnC{{l}_{4}}\]

    C)  \[\text{AlC}{{\text{l}}_{\text{3}}}\]

    D) \[B{{F}_{3}}\]

    Correct Answer: B

    Solution :

     Lewis acids are the compounds having a tendency to accept a pair of electron, e.g., \[B{{F}_{3}},AlC{{l}_{3}},Be{{F}_{2}},\]etc. So, \[\text{SnC}{{\text{l}}_{\text{4}}}\]is not a Lewis acid.
