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.
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.
Elevational diversity gradient (EDG) is an ecological pattern where biodiversity changes with elevation. The EDG states that species richness tends to decrease as elevation increases, up to a certain point, creating a "diversity bulge" at middle elevations.
The Department of Energy (Filipino: Kagawaran ng Enerhiya, abbreviated as DOE) is the executive department of the Philippine government responsible for preparing, integrating, manipulating, organizing, coordinating, supervising, and controlling all plans, programs, projects and activities of the Government relative to energy exploration, development, utilization, distribution and conservation.
You may be familiar with the Environmental Working Group (EWG) because they release a list of the most pesticide-filled produce every year called The Dirty Dozen. They also establish the produce ...
The Citizen Armed Force Geographical Unit, [1] variously called Citizens Armed Forces Geographical Unit, [1] Civilian Armed Forces Geographical Unit [1] and commonly referred to by its acronym CAFGU [1] (pronounced "kahf-goo") is an irregular auxiliary force of the Armed Forces of the Philippines focusing on anti-insurgency efforts in the countryside.
