There are 3 types of solvents commonly encountered: nonpolar, polar aprotic, and polar protic.(There ain’t such a thing as a non-polar protic solvent). 4. Nonpolar Solvents Have Little To No Dipole Moment These solvents have low dielectric constants (<5) and are not good solvents for cha...

To fully consider the reaction microenvironment of ILs, ONIOM calculation was used to study the solvent effect. At last, the above conclusions were further verified by the analysis of intermediates with charge, non-covalent interaction (NCI), and atoms in molecules (AIM) methods. The computational...
V. Rates of SN2 Reactions in Mixtures of Protic and Dipolar Aprotic Solvents The rates of reaction of methyl iodide with chloride ion in some protic-dipolar aprotic solvent mixtures have been measured. The rate-retarding effect of protic solvents at M concentration in dimethylacetamide is in the ...
Polar aprotic solvents, like tetrahydrofuran, are better solvents for this reaction than polar protic solvents because polar protic solvents will be solvated by the solvent hydrogen bonding to the nucleophile and thus hindering it from attacking the carbon with the leaving group. A polar aprotic ...

Based on previous work, we hypothesized that protic solvents would stabilize the negative ion and produce a greater response. Indeed we found that methanol was the best solvent. We also measured the response of each compound in methanol as a function of applied ESI voltage. Most compounds ...
The density (ρ), refractive index (n_D), dielectric constant (ε_s) and relaxation time (τ) of binary mixture of allyl bromide with polar protic solvent n-butanol including those of the pure liquids, were measured over the complete composition range. The esperimental data is used to ...
