The electromeric effect is a temporary effect observed in organic chemistry, particularly in the context of resonance structures and the behavior of pi bonds in double bonds (such as alkenes or carbonyl groups) when subjected to an external influence, such as an electric field or a nucleophile. It refers to the shift of electron density in a molecule, leading to the polarization of a sigma bond and the formation of a temporary dipole.
