Pyridine has a conjugated arrangement of six π-electrons that are delocalized over the ring. The atom is collapsed and appropriately follows the Hückel belief for ambrosial systems. In adverse to benzene, the electron body is not analogously broadcast over the ring, absorption the abrogating anterior aftereffect of the nitrogen atom. For this reason, pyridine has a dipole moment and a weaker beating stabilization than benzene (resonance activity 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). The electron localization in pyridine is aswell reflected in the beneath C-N ring band (137 message for the C-N band in pyridine vs. 139 message for C-C band in benzene), admitting the carbon-carbon bonds in the pyridine ring accept the aforementioned 139 message breadth as in benzene. These band lengths lie amid the ethics for the individual and bifold bonds and are archetypal of ambrosial compounds.
All the ring atoms in the pyridine atom are sp2-hybridized. The nitrogen atom "donates" its three alloyed electrons to the ring system, and its added electron brace lies in the atom plane, bulging outwards, in the even of the ring. This abandoned brace does not accord to the ambrosial arrangement but chiefly infuences the actinic backdrop of pyridine, as it calmly supports band accumulation via an electrophilic attack. However, because of the break of the abandoned brace from the ambrosial arrangement of the ring affects, the nitrogen atom can not display a absolute mesomeric effect.
