Polar aprotic solvent - Wikipedia

WitrynaThe term aprotic has been extended recently to include solvents that are unable to lose a proton, although they may have weakly basic properties. Some of these aprotic solvents have high dielectric constants (for example, N, N-dimethylformamide, dimethyl sulfoxide, and nitrobenzene) and are good solvents for a variety of substances.

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.
