WebThe +M effect, also known as the positive mesomeric effect, occurs when the substituent is an electron donating group. The group must have one of two things: a lone pair of electrons, or a negative charge. In the +M effect, the pi electrons are transferred from the group towards the conjugate system, increasing the density of the system.

WebApr 6, 2024 · The following reaction occurs: S + R → P. Here, S is the substrate or a reactant (a molecule on which the reaction is occurring). R is the attacking reagent that can be an electrophile or a nucleophile. This nucleophile makes changes to form a product P. So, under the reaction mechanism, we are going to study the electrophile and nucleophile. WebA general abbreviation for electrophiles is E+. All Lewis acids are electrophiles, but there are many more compounds that are also electrophiles that do not have a fully empty orbital.
