What is mesomeric effect in chemistry?
What is Mesomeric Effect? The polarity developed between atoms of a conjugated system by the electron transfer or pi–bond electron transfer is known as the Mesomeric effect.What is mesomeric effect types?
In chemistry, the mesomeric effect (or resonance effect) is a property of substituents or functional groups in a chemical compound. It is defined as the polarity produced in the molecule by the interaction of two pi bonds or between a pi bond and lone pair of electrons present on an adjacent atom.How many types of mesomeric effect are there?
If a substituent with a double bond or nonbonding electrons is directly attached to a conjugated system, the electron density and, as a result, the chemical shift will change. Further, there are two types of mesomeric effects: +M effect and -M effect according to types of mesomeric effects notes.- The main difference between resonance and the mesomeric effect is that the resonance effect describes how a molecule's lone pair of electrons and bond pair of electrons determine its chemical structure, whereas the mesomeric effect describes how a molecule's chemical structure is stabilized by using a functional group.
