    Which one is not Lewis acid?

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

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

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

    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,\[SnC{{l}_{4}}\]is not a Lewis acid.
