What This Document Is
This document is a pre-laboratory assignment for an organic chemistry experiment focused on the reduction of benzophenone using sodium borohydride. It prepares students for a hands-on laboratory session by outlining the chemical principles, safety considerations, and procedural steps involved in the reaction. The prelab explores the concepts of oxidation and reduction, specifically as they relate to carbon chemistry and the use of hydride reagents.
Why This Document Matters
This prelab is essential for students enrolled in Elements of Organic Chemistry (CHMY 211) at Montana State University. It serves as a critical preparation step *before* entering the lab, ensuring students understand the theoretical background and potential hazards. Completing this assignment allows students to safely and effectively perform the reduction reaction, analyze the results, and interpret spectroscopic data. It’s used to reinforce understanding of reduction reactions and laboratory techniques.
Common Limitations or Challenges
This prelab provides the foundational knowledge and planned procedure, but it does *not* substitute for actual laboratory experience. It does not include detailed troubleshooting advice for unexpected results, nor does it provide a complete analysis of the spectroscopic data obtained. Students will still need to apply their understanding during the experiment and interpret their own data.
What This Document Provides
The full document includes: a discussion of oxidation and reduction principles, an overview of sodium borohydride as a reducing agent, detailed safety information (SDS data) for benzophenone and sodium borohydride, a step-by-step procedure for the reduction reaction, instructions for product isolation and purification (recrystallization), guidance on obtaining melting points and performing Thin Layer Chromatography (TLC), and instructions for running an IR spectrum of the final product. This preview does *not* include the full experimental procedure, spectroscopic data interpretation, or detailed safety data sheets.
