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 . georgia driver\u0027s license check onlineWebSigma bonds (σ) are the first type of covalent bond found between two atoms formed by head-to-head overlap.
