- Benzene
- Electrophilic substitution
- uses electrophiles
- electron lovers
- Reagents conditions
- COCH3
- AlCl3 catalyst
- acylium ion in excess
- NO2+
- Conc H2SO4
- Conc HNO3+
- reflux 50c
- COCH3
- uses electrophiles
- Structure
- Planar
- 120 bond angle
- has 6 delocalised electrons
- delocalised electron ring
- all bond lengths are equal
- More stable than cyclohexane
- cyclohexane = 360KJmol-1
- 360-208=152KJ
- benzene has a lower energy
- benzene is more stable
- due to delocalised electrons
- spread of electrons equally between carbons
