Packet 5: Tossup 11

Derivatives of pyridine or this compound called PP2 and PP3 can be used to inhibit the corrosion of steel. Technetium catalyzes the oxidation of this compound by nitric acid, which causes problems when using this compound as a plutonium reducing agent to process nuclear fuel. (-5[1])Brady’s (-5[1])reagent, which contains a 2-4 di-nitrophenyl substituted (10[1])form of this compound, (10[1])can be used to distinguish ketones and aldehydes. Emil Fischer is reported to have accidentally (-5[1])discovered this compound’s phenyl derivative, (-5[1])which he later used as a reagent in his namesake indole synthesis. Hydrogen peroxide is used in methods of producing this compound (-5[1])that replaced the Olin–Raschig (10[1])process. (10[2]-5[1])This compound (10[1])cleaves carbonyls into alkanes in the Wolff–Kishner (10[2])reduction. (10[2])For 10 (10[1])points, (10[1]-5[1])name this compound commonly found in rocket fuel whose formula (10[3])is N2H4. (10[2])■END■ (10[7])
