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.
The Energy Watch Group (EWG) is an international network of scientists and parliamentarians. The EWG conducts research and publishes studies on global energy developments concerning both fossil fuels and renewables. The organization states that it seeks to provide energy policy with objective information. [1]

“This is an example of ‘know thy neighbor’ and those neighbors were able to help prevent this child from being permanently taken,” Hallandale Beach Police Capt. Megan Jones told NBC 6.
An electric effect influences the structure, reactivity, or properties of a molecule but is neither a traditional bond nor a steric effect. [1] In organic chemistry, the term stereoelectronic effect is also used to emphasize the relation between the electronic structure and the geometry (stereochemistry) of a molecule.
Office vacancies climbed more than 5% in six of the top 25 US markets this year, according to CommercialEdge. Sale prices, meanwhile, dropped again, down 9% from the average price in 2023.
