Inductive Effect vs. Resonance Effect: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 15, 2024
Inductive Effect is a permanent polarization of sigma bonds due to electronegativity differences. Resonance Effect is delocalization of electrons through pi bonds or lone pairs in a molecule.

Key Differences

The inductive effect refers to the electron-donating or withdrawing ability of substituents through sigma bonds due to electronegativity differences. In contrast, the resonance effect involves the delocalization of electrons through pi bonds or adjacent lone pairs, influencing molecular stability and reactivity.

In inductive effect, electron density shifts along the chain of atoms in a molecule, altering electron distribution without creating new electron paths. On the other hand, the resonance effect redistributes electrons across multiple structures, representing different electron arrangements.

The inductive effect is distance-dependent, diminishing with increasing distance from the substituent. Conversely, the resonance effect is not significantly distance-dependent, as it involves electron delocalization over a larger molecular framework.

Inductive effect is a permanent effect in a molecule, irrespective of external factors. In contrast, resonance effect often manifests in response to specific molecular interactions, such as bond formation or breaking.
