WebJan 23, 2024 · The conjugate base of benzoic acid is destabilized by electron-donating groups. This makes the acid less acidic Electron-withdrawing groups deactivate the benzene ring to electrophilic attack and make benzoic acids more acidic. Electron-donating groups The conjugate base of benzoic acid is stabilized by electron-withdrawing groups. WebSodium benzoate is a salt of the conjugate base, the OBz - or benzoate ion. Whenever sodium benzoate dissolves in water, it dissociates into its ions. The benzoate ion then acts as a base toward water, picking up a …
