FAQs on Mesomeric effect - Organic Chemsitry Video Lecture - Class 11

1. What is the mesomeric effect in organic chemistry?

Ans. The mesomeric effect, also known as resonance effect, refers to the redistribution of electrons through a sigma bond or a pi bond within a molecule. It occurs due to the delocalization of electrons, resulting in the stabilization of the molecule.

2. How does the mesomeric effect affect the stability of a molecule?

Ans. The mesomeric effect can either increase or decrease the stability of a molecule, depending on the nature of the group involved. Electron-withdrawing groups (EWG) tend to decrease the stability of a molecule, while electron-donating groups (EDG) increase the stability. This effect is attributed to the redistribution of electron density within the molecule.

3. Can you provide an example of the mesomeric effect in action?

Ans. Yes, a classic example of the mesomeric effect is found in the resonance structures of the benzene molecule. The delocalization of pi electrons in benzene leads to its stability and the equal bond lengths between carbon atoms.

4. How does the mesomeric effect influence the reactivity of a molecule?

Ans. The mesomeric effect greatly influences the reactivity of a molecule. Electron-donating groups (EDG) enhance the reactivity of a molecule by increasing its electron density, making it more susceptible to nucleophilic attacks. On the other hand, electron-withdrawing groups (EWG) decrease the reactivity by withdrawing electron density from the molecule.

5. Is the mesomeric effect limited to aromatic compounds only?

Ans. No, the mesomeric effect is not limited to aromatic compounds. It can also occur in non-aromatic compounds, such as carbonyl compounds, alkenes, and carbocations. In these cases, the mesomeric effect plays a crucial role in determining the stability and reactivity of the molecules.
