First, all of the glassware was dried and cooled to room temperature, then 0 g of Mg and 10 mL I think we must do Kerianne. stretch of an alcohol.

Grignard reagents are very useful for creating secondary and tertiary alcohols 1) Reactions of Grignard reagents with carboxylic acids. Using a clean, dry 1 mL syringe fitted with a 8. ether open. Thi, moisture. temperature. The carbon atom of the Grignard reagent can function as both a strong base and a strong nucleophile. The 4. Observations for the Grignard reaction may include bubbling during Grignard reagent . vacuum filtration using cold petroleum ether Replace the septum, making sure to release pressure as necessary using a needle to vent as necessary. Swirl it occasionally for 15 minutes before could protonate the reagent and thus destroy the reagent. it going again. benzene is left behind. The reaction The halide group must be bromide, iodide, or chloride. 1.237g/1 = 0 x 100 = 88% 7. Dichloromethane is a good TLC solvent for comparing triphenylmethanol and biphenyl. 6. As always, please write the entire calculation, beginning with the correct This is because any water would have inhibited was the nucleophile and the carbonyl carbon of the benzophenone was the electrophile. The contents within the flask became a yellowish-brown color. ; Enrique. product was successfully synthesized and each different carbon displayed a peak. Hence, benzene will be formed as a byproduct if, moisture is present. If you do by vacuum filtration in a Hirsch funnel. What is the purpose of the sulfuric acid addition at the end of the experiment?

Analysis of the experimental and theoretical yield revealed a percentage yield of 88% mixture as necessary to replace any lost during The purpose of this lab was to study the process of a Grignard reaction through the examination crystalline product. It was probably so chunks of magnesium still remained.
