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. WebPolar solvents can be further divided into protic and aprotic. Polar protic solvents are capable of hydrogen bonding because they contain at least one hydrogen atom connected directly to an electronegative atom (such as O-H or N-H bonds). They solvate cations and anions effectively. night of the proms hamburg 2023

6.5. Lewis acids & bases, electrophiles & nucleophiles

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 ... WebPolar aprotic solvents (e.g., DMSO, acetone, acetonitrile, DMF) are very effective in solvating cations, but not nearly so effective in solvating anions. Because anions are only poorly solvated, they participate readily in SN reactions, and nucleophilicity parallels basicity: F- > Cl- > Br- > I- Polar protic solvents (e.g., water, methanol)
