RankGuru · Accepted Answer

**Friedel-Crafts Alkylation** is used to introduce an alkyl group into the benzene ring.
- Reagents: Alkyl halide ($R-Cl$) and a **Lewis Acid catalyst** such as anhydrous **$AlCl_3$**.
- Function of $AlCl_3$: It acts as a Lewis acid to generate the electrophile (carbocation, $R^+$) by accepting a lone pair from the halogen.
Reaction: $C_6H_6 + RCl \xrightarrow{AlCl_3} C_6H_5R + HCl$
- Limitations include carbocation rearrangement and polyalkylation.
