This scientist names a type of reaction vessel that contains a side-arm with a stopcock. For 10 points each:
[10m] Name this scientist who devised a setup for air-free experiments with manifolds hooked up to a vacuum pump and a source of inert gas.
ANSWER: Wilhelm Johann Schlenk [accept Schlenk line or Schlenk Flask or Schlenk manifold]
[10e] Schlenk co-names a class of hydrocarbons that are paramagnetic due to having two of these unstable species, which contain unpaired electrons.
ANSWER: free radicals
[10h] With his son, Schlenk discovered that Grignard (“GRIN-yard”) reagents exist in solution at an equilibrium with these other organomagnesium compounds used in metalation reactions. “Turbo” varieties of these compounds have improved solubility and reactivity through the addition of lithium chloride.
ANSWER: Hauser bases [or magnesium amide bases; accept Turbo-Hauser bases]
