Expert Answer:

  • Chemical bonds are formed when two nuclei share a pair of electrons between them.
  • These bonds are considered combinations of overlapping one-electron atomic orbitals.
  • The bond is strongest when the two electrons are confined to a region between the two nuclei. This type of bond is described as a localised bond.
  • Delocalised bonding electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or a covalent bond.
  • For example, in Benzene molecule, the delocalisation of electrons is indicated by circle.
  • A moleculae with delocalised bonding is more stable than a molecule with localised bonding.
