Oxidation of Benzoin to form Benzil PURPOSE The purpose of the experiment is using ammonium nitrate and cupric acetate solution using the copper (II) ion as an oxidative catalyst to yield benzil from benzoin. The benzoin collected from a previously executed experiment (Maras-Lindeman 2011)was oxidized with the help of the above named oxidizing catalysts. Validation of successful oxidation was done by comparing melting point of yielded product to that of melting point labeled in literature for benzil, and IR spectroscopy. THEORY Chemical reactions that pertain to the exchange of electrons are called oxidation-reduction reactions, also known as redox reactions and are popular when synthesizing many products (Smith 2009). In simple terms, redox reactions are the loss or gain of C-H bonds. Specifically

    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.
