Question
What do you mean by delocalisation of 
-electrons?
Solution
Delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or a covalent bond. For example, all carbon atoms in benzene are sp2-hybridised. The 
-electrons are delocalised throughout the whole molecule. The delocalisation of 
-electrons to a greater space causes a decrease in energy and hence increases the stability of benzene molecule. Delocalisation of electrons is possible in coplanar molecules.
