Revision:Why is benzene stable?

From The Student Room

TSR Wiki > Study Help > Subjects and Revision > Revision Notes > Chemistry > Why is benzene stable?


  • The p orbitals on each carbon atom in benzene overlap
  • There is delocalisation of electrons in the ring (not 3 localised C==C double bonds)
  • This makes benzene more thermodynamically stable than predicted
  • It therefore undergoes substitution reactions rather than addition reactions because addition reaction break the delocalisation in the ring. e.g The nitration of benzene results in a loss of H+ which is replaced by NO2+
