Themesomeric effectorresonance effectinchemistryis a property ofsubstituentsorfunctional groupsin achemical compound. The effect is used in a qualitative way and describes the electron withdrawing or releasing properties of substituents based on relevantresonance structuresand is symbolized by the letterM. The mesomeric effect is negative (-M) when the substituent is an electron-withdrawing group and the effect is positive (+M) when based on resonance and the substituent is an electron releasing group.
