How does alcl3 act as a catalyst
Webhow does AlCl3 act as a catalyst between chlorine and benzene acts as an electrophile … WebHalogens need a Lewis Acidic catalyst to activate them to become a very strong electrophile. Examples of these activated halogens are ferric halides (FeX3) and aluminum halides (AlX3) where X= Br or Cl. In order to make bromine electrophilic enough to react with benzene, we use the aid of an aluminum halide such as aluminum bromide.
