Molecular ions ionic liquids, electrostatic properties

When classifying these anions, it is important to remember that water, unlike other liquids, exhibits good solvent properties for salts because of its specific structure and the special interaction mechanism between the ion and the water molecule. When an ion is solvated by water, hydrogen bonds are broken (cavity effect) and the water structure is destroyed. The larger the ion, the higher the energy required for the formation of a cavity with molecular dimension. On the other hand, electrostatic ion-dipole interactions occur that lead to the formation of a new structure. Thus, the smaller the ionic radius and the higher the...
