WitrynaIn this paper we report on the transport properties of protic and aprotic ionic liquids of the imidazolium cation (C 2 C 1 Im + or C 2 HIm +) and the TFSI − or TfO − anion as a function of added water. We observe that the self-diffusion coefficient of the ionic species increases upon addition of water, and that the cation diffuses faster than the anion in … WitrynaIn addition to acetone, three other commonly used polar aprotic solvents are acetonitrile, dimethylformamide (DMF), and dimethyl sulfoxide (DMSO). In biological chemistry, where the solvent is protic (water), the most important implication of the periodic trends in nucleophilicity is that thiols are more powerful nucleophiles than alcohols.

Actually the polar aprotic solvent favors the nucleophilicity of the base/nucleophile and as a result favors the S N 2 to occur over E2. In the case of protic solvent the E2 is favored as the close approach of nucleophile/base is hindered due to solvolysis.
