Difference Between EDG And EWG
Property |
EDG |
EWG |
Definition | EDG stands for an electron-donating group | EWG stands for an electron-withdrawing group |
Effect on Resonance | Increases electron density in pi systems | Decreases electron density in pi systems |
Effects on Reactivity | Increases the rate of reactions that involve a nucleophilic attack. | Increases the rate of reactions that involve an electrophilic attack. |
Effects on Molecular Properties | Increases boiling point due to the formation of hydrogen bonds with water molecules. | Decreases boiling point due to the absence of hydrogen bonding |
Examples | -OH, -NH2, -OR, -NHR | -NO2, -CN, -COOH, -C=O |
Difference Between EDG And EWG
The EDG and EWG, both are electrophilic aromatic directing groups. And these are forms of substituents that we can find in organic compounds. If you’ve looked at a molecule’s structure, you might have noticed that some atoms are labeled with an “E” or “EWG” while others are labeled with an “E” or “EDG.” These abbreviations refer to electronic effects that can influence the reactivity and properties of a molecule. In this article, we will discuss the difference between EDG and EWG.
