Is methanol protic or aprotic
Witryna21 lip 2010 · 19. Jul 21, 2010. #5. Yes it's A. If the reaction was in aprotic solution, it would definitely react a lot faster because the aprotic solvents would stabilize the products formed. but if it were a protic solvent, the reaction would just react slower since the protic solvent forms H-bonds with the KOH and stabilizes that instead. WitrynaIn this study, we explore the solvent-assisted desorption of a penetrant (2,5-lutidine) in polyurethane with aprotic (acetonitrile) and protic (methanol) solvents. Chemical interactions between ...

Polar protic solvents can form hydrogen bonds with water to dissolve in water and are best for dissolving polar reactants such as ions.
Witryna23 sty 2024 · These solvated species are more stable and less reactive than the unsolvated "naked" anions. Polar, aprotic solvents such as DMSO (dimethyl sulfoxide), DMF (dimethylformamide) and acetonitrile do not solvate anions nearly as well as methanol, but provide good solvation of the accompanying cations.
Witryna15 gru 2024 · Polar aprotic solvents is a group solvents with medium range of polarity.
