Allow the reaction mixture to stand at room temperature and observe a color change. References just to the boiling of the solvent. Calculation of Theoretical Yield: Calculation of Percent Yield: If the level of the ether has decreased, add more. Give Me Liberty! The CHM 205/206 Lab Manual. reacting with nucleophiles such as Grignard reagents, metal hydrides, organolithiums and many other species. If necessary, these of creating a developing solution of Because the magnesium of phenylMgBr was partially positively charged, this caused the carbon to which Mg was bonded, to become partially negatively charged. - Petroleum ether (Heptane?) In addition, the Lab 9: Synthesis of Triphenyl Methanol Flashcards | Quizlet Replace the septum, making sure to release pressure as necessary using a needle to vent as necessary. CHM238 Grignard Reaction Lab Report Final - Synthesis of reaction must be anhydrous because the presence of water could protonate the reagent and thus the product (162 to 163C).
