Round 4: Tossup 15

A very reactive one of these substances made by mixing n-butyllithium and potassium tert-butoxide is named for Manfred Schlosser. (15[1])In organic chemistry, (15[1])nucleophiles typically act as these substances. (15[1]-5[1])The “super” variety of these substances (15[1])are more powerful than a proton sponge. Boron trifluoride is one of these substances according to a theory that defines them as (*) electron pair donors, devised by Gilbert Lewis. Saponification is catalyzed by one of these substances such as lye. Svante Arrhenius defined these substances as hydroxide donors. For 10 points, name these substances that have a pH greater than 7. ■END■ (10[1])
