This effect is also known as a positive inductive effect (+ I effect) or electron-donating inductive effect. Note: Inductive effect considers the partial shifting of σ-electrons or a single bond only. Order of Inductive Effect

WitrynaCorrect option is D) The order of reactivity towards electrophilic addition reaction depends upon the electron donating ability of the groups attached to the cyclohexene ring. Order of electron donating power: Cl>OH>CH 3 (iii) is most reactive towards EAR due to the high electron donating power of Cl atom, followed by (ii) and (iv). WitrynaThe polar effect or electronic effect in chemistry is the effect exerted by a substituent on modifying electrostatic forces operating on a nearby reaction center.

WitrynaAn 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 …

In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen. This alkoxy group has the formula R−O−CH3. On a benzene ring, the Hammett equation classifies a methoxy substituent at the para position as an electron-donating group, but as an electron-withdrawing group if at the meta position.
