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.
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]
Research Papers in Economics (RePEc) is a collaborative effort of hundreds of volunteers in many countries to enhance the dissemination of research in economics. The heart of the project is a decentralized database of working papers , preprints , journal articles, and software components. [ 1 ]

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.
The National Library of Economics (ZBW – Leibniz Information Centre for Economics) is the world's largest research infrastructure for economic literature, online as well as offline. The ZBW is a member of the Leibniz Association and has been a foundation under public law since 2007.
Average mortgage rates edge higher for 30-year and 15-year terms as of Wednesday, December 18, 2024, as the Federal Reserve is set to conclude its final policy session of the year.
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 ...
