what is positive mesomeric (+M) effect give an example
Answers
Answer:
If the π electrons move away from the group and towards the rest of the molecule, the effect is called a +M effect . An example is the donation of electrons from an amino group into a benzene ring, putting δ− charges on the ortho and para positions.
The mesomeric effect in chemistry is a property of substituents or functional groups in a chemical compound. ... The mesomeric effect is negative (–M) when the substituent is an electron-withdrawing group and the effect is positive (+M) when the substituent is an electron releasing group.
