Vedclass · Answer

(D) Friedel-Crafts reactions require a Lewis acid catalyst to generate the electrophile. Lewis acids are electron-pair acceptors. $FeCl_3$,$FeBr_2$,and $AlCl_3$ are effective Lewis acids because they have vacant orbitals and can accept electron pairs. $NaCl$ contains the $Na^+$ ion,which has a stable inert gas configuration $(1s^2 2s^2 2p^6)$. Due to this stable configuration,$Na^+$ has a very low tendency to accept electrons and therefore does not act as a Lewis acid in Friedel-Crafts reactions.
