What does resonance effect mean?
- The resonance effect is the polarity produced in a molecule by the interaction between a lone electron pair and a pi bond or the interaction of two pi bonds in adjacent atoms. It is usually found in molecules with conjugated double bonds or in molecules having at least one lone pair and one double bond.
What are examples of the inductive effect?
- Inductive effect is a partial shifting/displacement of ? electrons towards a more electronegative atom of ? bond. This means ? (or single bond electrons) shifts towards a more electronegative atom. Because of this, partial charges develop. Let’s take inductive effect examples: 1. C-C-C-X.
What does inductive effect mean?
- The Inductive Effect . The inductive effect, sometimes written as "the -I Effect" in literature, is the distance-dependent phenomenon by which the charge of a chemical bond affects orientation on adjacent bonds in a molecule, producing a permanent state of polarization.
Are electromeric and resonance effects the same?
- This effect is a consequence of resonance and is seen in compounds that contain a double bond that is separated from another double bond or a lone pair of electrons by a single bond. The electromeric effect is an intramolecular movement of electrons from a pi bond to another atom in the molecule due to attack by a reagent.
