WebDicarboxylic acid definition, any of the organic compounds that contain two carboxyl groups. See more. WebInductive effect. In chemistry, the inductive effect in a molecule is a local change in the electron density due to electron-withdrawing or electron-donating groups elsewhere in the molecule, resulting in a permanent dipole in a bond. [1] It is present in a σ (sigma) bond, unlike the electromeric effect which is present in a π (pi) bond .
