WebRegarding the solvent, polar aprotic solvents such as DMSO, DMF, acetone or acetonitrile are popular choices for S N 2 reactions, because rates are generally faster than with polar protic solvents (water, alcohols, etc.). This is because the nucleophile is almost “naked” in aprotic solvents, whereas in polar protic solvents it is surrounded ... WebDec 3, 2014 · A polar aprotic solvent does not have a hydrogen atom that can participate in hydrogen bonding. Some typical polar aprotic solvents are In all of them, the negative ends of the dipoles point away from the molecule. It is easy for them to solvate cations. The positive ends of the dipoles are closer to the middle of the molecule.
