Benzene Reactions
- Nitration (NO2)
- Electrophile: NO2+
- Benzene + HNO3 -> nitrobenzene
- HNO3 + H2SO4 -> NO2+ + HSO4- + H2O
- Temperature must be below 50 or
dinitrobenzene will form
- Acylation
- Acyl Group: CH3 - C=O
- ALCl3 + CH3 - C=O - Cl -> AlCl4- + CH3-C+=O
- Alkylation
- Use halogenoalkane with AlCl3 as a
halogen carrier to generate the
electrophile
- AlCl3 + CH3Cl -> AlCl4- + CH3+
- CH3+ = Electrophile
- AlCl4- + H+ -> AlCl3 +HCl
- Halogenation
- Electrophile must be positive
- Halogen carrier, FeBr3, AlBr3
- FeBr3 + Br2 -> FeBr4- + Br+
- Polarises and breaks Br-Br
bond
- FeBr4- + H+ -> FeBr3 +HBr
