The mesomeric effect (or resonance effect) in chemistry is a property of substituents or functional groups in a chemical compound. It is defined as the polarity produced in the molecule by the interaction of two pi bonds or between a pi bond and lone pair of electrons present on an adjacent atom. This change in electron arrangement results in the formation of resonance structures that hybridize into the molecule's true structure. The pi electrons then move away from or toward a p… WebThe mesomeric effect is discussed in terms of a mixing of the `locally excited' states of the hydrocarbon, and the `electron transfer' states. If the substituent behaves as an electron …
