Inductive Effect occurs when a molecule experiences an uneven distribution of bonding electrons, leading to the formation of a permanent dipole in that molecule. This redistribution of electrons is caused due to electron-donating or electron-withdrawing groups in the molecule. Learn about the inductive effect in organic chemistry, a local change in electron density due to electron-withdrawing or electron-donating groups. Find out how it affects bond polarization, acidity, basicity, and fragmentation of molecules. Negative inductive effect (-I effect ): Due to electron-withdrawing nature of the group, electron density decreases. Thus, basic nature is decreased and acidic nature is increased. Inductive effect is an effect that occurs when the σ-bond in a molecule is polarised. In this article, we will discuss the different types of inductive effects .
