The Fridel crafts catalyst "𝐴𝑙𝐢𝑙3" used in the substitution reactions of Benzene is good:

Correct answer: D. Bear all properties

  • A. Electrophile
  • B. Lewis acid
  • C. Electron deficient specie
  • D. Bear all properties

Explanation

The function of AlCl3(anhydrous), in the Friedel-Craft reaction, is to produce electrophile, which later adds to the benzene nucleus. This electrophilic aromatic substitution allows the synthesis of monoacetylated products from the reaction between arenes and acyl chlorides or anhydrides. The products are deactivated and do not undergo a second substitution. Normally, a stoichiometric amount of the Lewis acid catalyst is required for both the substrate and the product form complexes.

About Alkyl Halides

Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
