2. Electron-withdrawing group - Wikipedia

   en.wikipedia.org/wiki/Electron-withdrawing_group

   An electron-withdrawing group (EWG) is a group or atom that has the ability to draw electron density toward itself and away from other adjacent atoms. [1] This electron density transfer is often achieved by resonance or inductive effects.

3. Captodative effect - Wikipedia

   en.wikipedia.org/wiki/Captodative_effect

   Delocalizing the radical ion stabilizes the transition state structure. As a result, the energy of activation decreases, enhancing the rate of the overall reaction. According to the captodative effect, the rate of a reaction is the greatest when both the EDG and EWG are able to delocalize the radical ion in the transition state structure. [7]

4. Electrophilic aromatic directing groups - Wikipedia

   en.wikipedia.org/wiki/Electrophilic_aromatic...

   An electron donating group (EDG) or electron releasing group (ERG, Z in structural formulas) is an atom or functional group that donates some of its electron density into a conjugated π system via resonance (mesomerism) or inductive effects (or induction)—called +M or +I effects, respectively—thus making the π system more nucleophilic.

5. Inductive effect - Wikipedia

   en.wikipedia.org/wiki/Inductive_effect

   The inductive effect can be used to determine the stability of a molecule depending on the charge present on the atom and the groups bonded to the atom. For example, if an atom has a positive charge and is attached to a -I group its charge becomes 'amplified' and the molecule

7. Diels–Alder reaction - Wikipedia

   en.wikipedia.org/wiki/Diels–Alder_reaction

   For example, in a normal-demand scenario, a diene bearing an electron-donating group (EDG) at C1 has its largest HOMO coefficient at C4, while the dienophile with an electron withdrawing group (EWG) at C1 has the largest LUMO coefficient at C2. Pairing these two coefficients gives the "ortho" product as seen in case 1 in the figure below.
