ETOX 102A Homework #4 Key 1). Hydroxyl radicals are among the most reactive and highly unstable of environmental oxidants. They may be generated by various reaction pathways, such as Fenton reaction or by sunlight. Draw an example of how a hydroxyl radical is generated by both a Fenton reaction and by sunlight. (3 pts) Fenton Reaction: Fe 2+ + H 2 O 2 Fe 3+ + - OH + . OH (1.5 pts) Hydrogen Abstraction : C 6 H 6 + . OH H 2 O + . C 6 H 5 + . OH C 6 H 5 –OH (1.5 pts) 2). Catalytic converters were installed in automobiles to reduce the amount of combustion gases released into the environment. Please draw a reaction diagram to explain how NO (nitric oxide) is converted into N

Unformatted text preview: 2 with the help of a catalytic converter (also include the net rreaction). (3 pts) Catalytic converters use CO as a reducing agent along with Pt, Pd, and Rh as reducing catalysts. (1 pt) NO + CO N 2 O + CO 2 (0.5 pt) N 2 O + CO N 2 + CO 2 (0.5 pt) N et Reaction : NO + 2CO N 2 + 2CO 2 (1 pt) 3). Please diagram the general reaction mechanism of base-catalyzed hydrolysis. Would base-catalyzed hydrolysis be more likely to occur in freshwater or seawater? Why (please briefly explain)? (3 pts) (scheme is in lecture notes) More likely to occur in freshwater due to alkaline ph (more hydroxyl groups available)...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
