An electron withdrawing group increases the acidity carboxylic acid. It disperses negative charge by inductive/ resonance effect and stabilizes the carboxylate ion. Thus, p-nitro benzoic acid (pKa 3.41) is more acidic than benzoic acid (pKa 4.19). Nitro group is electron withdrawing group. Was ...
Carbonyl is a functional group characterized by a carbon atom double-bonded to an oxygen atom (C=O). Ketones are organic compounds containing a carbonyl group bonded to two alkyl or aryl groups.
Nitro is an electron-withdrawing group. Individual Intended for a single person as opposed to more than one person. Individual personal pension; individual cream cakes Group (sociology) A subset of a culture or of a society. Individual Not divisible without losing its identity. Group (military) ...

What is the difference in the electron withdrawing groups in electrophilic aromatic substitution (ENS) and nucleophilic aromatic substitution (NAS)? Write out the mechanism for the Electrophilic Aromatic Substitution of Benzoic Acid to produce m-nitrobenzoic Acid?
Michael Reaction: In order to create additional electrophilic centers and speed up the process, this reaction will involve a nucleophilic addition on molecules having electron-withdrawing groups. This reaction takes place onα&βunsaturated carbonyl groups. ...

Are carbanions nucleophiles or electrophiles? Carbanions are nucleophiles as they have excess electrons and tend to donate them. 10 What determines the stability of a carbanion? The stability of a carbanion is enhanced by the presence of electron-withdrawing groups and the overall molecular structure...
