    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.

    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]

    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.

    Description: In this paper, Becker demonstrates that neoclassical economic demand curves follow simply from the fact that compensated price changes in the goods available to consumers with fixed budget sets cause corresponding shifts in the consumption opportunity sets of those consumers and thus do not require any assumptions about the ...
