- 1Why is benzene less reactive than alkenes?
- 2In cyclohexene the pi bond is made by sideways overlap of p orbitals on adjacent carbon atoms. Whereas for benzene, the pi bond is made by the sideways overlap of p orbitals on all 6 carbons atoms adjacent to each otherTherefore on benzene the 6 pi electrons are delocalised over 6 carbon atoms
On cyclohexane the two pi electrons are localised between the two carbon atoms - 3Therefore cyclohexene has a higher pi electron density than benzene and will attract electrophiles more strongly as it induces a bigger dipoleSo alkenes are more reactive than benzene
