Non-
protogenic (in a given situation). (With extremely strong
Brønsted acids or
bases, solvents that are normally aprotic may accept or lose a
proton. For example, acetonitrile is in most instances an aprotic solvent, but it is
protophilic in the presence of concentrated sulfuric acid and
protogenic in the presence of potassium
tert-butoxide. Similar considerations apply to benzene, trichloromethane, etc.)
