Web16 sep. 2024 · The difference between what is expected for three isolated double bonds (3 × −118.4 = −355.2 kJ mol −1) and what is actually found for benzene amounts to ΔH 298 = −355.2 + 206.0 = −149.2 kJ mol −1 and is sometimes cited as the quantitative reflection of the stability of the aromatic π-system in benzene. WebIn the simple aromatic ring of benzene, the delocalization of six π electrons over the C 6 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 …
