WebJun 22, 2024 · Dynamics of solvent molecules restricted in poly (acryl amide) gels immersed in solvent mixtures of acetone–, 1,4-dioxane–, and dimethyl sulfoxide–water … WebAug 17, 2024 · The most suitable method is using the dielectric constants. The dielectric constant (ε) of a solvent is a measure of its polarity. The higher the dielectric constant of a solvent, the more polar it is. Let’s look at chloroform, CHCl 3, as an example to understand this: Chloroform has tetrahedral molecular geometry. Web(between 5 and 20) make adequate general-purpose solvents for a wide range of reactions. Aprotic solvents with dielectric constants greater than 20 and large dipole moments can dissolve charged species such as various anions used as nucleophiles. Without hydrogen bonding in the solvent, these nucleophiles are relatively free in rockface rumble
