WebIn the diagram below, the p orbitals have combined, and the π-electrons are delocalized. On average all of the ring bonds are identical. Unlike in the next the example below, the delocalized electrons in benzene are held within the molecule and are not free to move through the bulk material. Example 2: In the simple aromatic ring of benzene, the delocalization of six π electrons over the C6 ring is often graphically indicated by a circle. The fact that the six C-C bonds are equidistant is one indication that the electrons are delocalized; if the structure were to have isolated double bonds alternating with discrete single bonds, the bond would likewise have alternating longer and shorter lengths.
