"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. It is present in a σ (sigma) bond, unlike the electromeric effect which is present in a π (pi) bond. The halogen atoms in an alkyl halide are electron withdrawing while the alkyl groups have electron … " - Predict basicity induction

The lone pair on the right of the oxygen picked up a proton, formed a bond, and so we get this with a plus one formal charge on the oxygen. reclaimed storeWebK a refers to the degree of dissociation of the acid. If the acid dissociates to a large extent, i.e. high [ H X +] ions, then its K a will be high. When you convert a high K a to p K a, p K a will be low (just a mathematical relationship). Thus, high K a = low p K a = strong acid. High K b = low p K b = strong base. reclaimed stone wallingWebAug 22, 2024 · 🎯 Want to ace chemistry?
