    Which of the following cannot be used in Friedel-Craft?s reaction?

    A) \[FeC{{l}_{3}}\]                                

    B)  \[FeB{{r}_{2}}\]

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

    D) \[NaCl\]

    Correct Answer: D

    Solution :

                     All cations are expected to act as Lewis acid since they are electron deficient in nature. However; cation such as\[N{{a}^{+}},{{K}^{+}}\]etc (inert gas configuration) have a very little tendency to accept electrons. Therefore, they do not act  as Lewis acids in Friedel-Craft's reaction.
