How do electron withdrawing groups work?
An electron releasing group or ERG (may also be called electron donating groups or EDG’s) releases electrons into a reaction center and as such stabilizes electron deficient carbocations.

An electron releasing group or ERG (may also be called electron donating groups or EDG’s) releases electrons into a reaction center and as such stabilizes electron deficient carbocations. An electron withdrawing group or EWG draws electrons away from a reaction center.Click to see full answer. Also question is, what do electron withdrawing groups do?An electron withdrawing group (EWG) draws electrons away from a reaction center. When this center is an electron rich carbanion or an alkoxide anion, the presence of the electron-withdrawing substituent has a stabilizing effect.Furthermore, are activating groups electron withdrawing? The activating groups are mostly resonance donors (+M). Although many of these groups are also inductively withdrawing (–I), which is a deactivating effect, the resonance (or mesomeric) effect is almost always stronger, with the exception of Cl, Br, and I. Beside this, what are examples of electron withdrawing groups? Electron withdrawing groups have an atom with a slight positive or full positive charge directly attached to a benzene ring. Examples of electron withdrawing groups: -CF3, -COOH, -CN. Electron withdrawing groups only have one major product, the second substituent adds in the meta position.Are R groups electron donating or withdrawing?Alkyl substituents (e.g. -CH3, -CH2CH3) are also electron donating groups – they activate the aromatic ring by increasing the electron density on the ring through an inductive donating effect. This is the same effect that allows alkyl groups to stabilise simple carbocations.
