2-Chloropropane and AlCl₃ give the isopropyl cation; benzene attacks it and loses H⁺ to give cumene.

## Mechanism step by step

AlCl₃ turns an alkyl halide into a carbocation that alkylates the ring

1. **Carbocation** – AlCl₃ pulls chloride off carbon
2. **Attack** – The ring attacks the carbocation
3. **Deprotonation** – Cl⁻ (from AlCl₄⁻) takes H⁺; AlCl₃ is regenerated

## Key points

- Primary halides rearrange: 1-chloropropane also gives cumene.
- The alkylated ring is more reactive than benzene, so polyalkylation is common.
- Strongly deactivated rings (nitrobenzene) and anilines do not react.
- Acylation then reduction avoids both problems.
