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. (-5[1])In organic chemistry, nucleophiles (-5[1])typically act as these substances. The “super” variety of these substances (-5[2])are more powerful than (-5[1])a proton sponge. (-5[1])Boron trifluoride is one of these substances according to a theory that defines them as (*) electron (10[1])pair donors, devised (-5[1])by Gilbert Lewis. Saponification is catalyzed by one of these substances such (-5[1])as lye. (10[1]-5[1])Svante (10[1])Arrhenius defined these substances as hydroxide donors. (10[1])For 10 points, name these substances that have a pH (-5[1])greater than (10[1])7. (10[2])■END■ (10[9])
