Organic Chemistry Lab I (CHEM 237) Experiment 10: Phase Transfer Catalysis 100% Solved Objective: To examine the use of a phase transfer catalyst to effect an SN2 reaction in dichloromethane solution. The reaction will be conducted without extraction for product isolation. List the procedural steps, from start to finish, that are required to convert 2-naphthol and allyl bromide into allyl 2-naphthyl ether. - The reaction is performed on a small scale by mixing the alcohol, the haloalkane, ...

Organic Chemistry Lab I (CHEM 237) Experiment 10: Phase Transfer Catalysis 100% Correct List the procedural steps, from start to finish, that are required to convert 2-naphthol and allyl bromide into allyl 2-naphthyl ether. The reaction is performed on a small scale by mixing the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial. Sodium hydoxide (base) is added to initiate the reaction. The reaction flask is covered and stirred to conduct reaction to prevent evaporation...

TLC Lab Report 5 Study Guide Rated A+ Thin Layer Chromatography consists of three parts: The analyte, the stationary phase, and mobile phase. Match each of these terms to what it was in our experiment. 1. Mobile Phase 2. Analyte 3. Stationary Phase The dominate reason by which analytes are retained on a TLC plate is? If the distance from the origin (start line Figure 10.2) to the middle of a spot is 4.8 cm and the distance from the middle of the same spot to the solvent front (end line F...
