Question

Terrence Collins’s group has popularized green catalysts for this type of reaction that use tetra-amido macro·cyclic ligands. The Mars–van Krevelen model describes hetero·geneous catalysis of these reactions using platinum-doped gold or ceria nano·particles. Metallo·enzymes that normally catalyze these reactions using a “radical rebound” are a common starting point (10[1])for directed evolution by Frances Arnold’s group. Supercritical water and activated sludges (10[1])catalyze this type of reaction to degrade halo·genated organic solvents. The platinum atom in a two-way catalytic converter catalyzes this type of reaction (10[1]-5[1])on carbon monoxide. The heme iron atom in a cytochrome P450 enzyme catalyzes (-5[1])this general type (10[1]-5[1])of reaction (-5[2]) for instance, (-5[1])to convert alkanes to alcohols. (10[5]-5[3])For 10 points, (10[1])name these reactions (-5[1])in which molecules lose electrons. (10[3])■END■ (10[10]0[2])

ANSWER: oxidations [or word forms like oxidize or oxidizing; accept catalytic oxidations; accept monooxygenation; accept hydroxylation; accept peroxidation; accept dehydrogenation; prompt on redox or reduction-oxidation reactions by asking “what type of reaction produces the desired product?”; prompt on C-H activation or carbon-hydrogen activation until “activated” is read by asking “what is the general class of reaction?”; reject “dehydration,” “reduction,” “hydrogenation,” or “combustion”]
