Hello!
The polarity developed between atoms of a conjugated system by the electron transfer or pi-bond electron transfer is known as the mesomeric effect. Mesomeric effect occurs when pi bonded electrons move away or toward a substituent group in a conjugated orbital system.
The mesomeric effect can be classified into two types - +M effect and -M effect.
+M effect - positive mesomeric effect.
-M effect - negative mesomeric effect.
Hope the answer was helpful, ALL THE BEST.
Thank You
