Question

What is negative resonance effect?

Answer 1

Answer:

Explanation:

The Negative resonance effect happens when the groups withdraw the electrons from the other molecules by the delocalization process. Usually, the groups are denoted either by -R or -M. The molecular electron density is said to decrease in this process.

Negative Resonance Effect- Negative resonance effect occurs when the groups withdraw the electrons from other molecules by the process of delocalization. The groups are usually denoted by -R or -M. In this process, the molecular electron density is said to decrease. For example- −NO2,C=O,−COOH,−C≡N.
