EXPERIMENT 3: GRINGNARD REACTION / synthesis of 2 methyl 2 butanol.
pls I need your help on this post lab questions.
Post-Lab Questions: 1. What would happen to the yield of the product if you used regular lab grade ether instead of anhydrous ether to dissolve the carbonyl compound in steps 2 and 3 above? Write a chemical equation illustrating the process. Use structural formulas or skeletal structures. 2. What is the formula of the magnesium salt of the alcohol formed after the carbonyl compound has been added to the Grignard reagent? Use structural formulas or skeletal structures. In Step 7. what is the molarity of the dilute HCI solution you prepared? If you were to use the entire solution, how many moles of HCI would you have added? 3. 4. What is the purpose of adding the HCI solution in Step 7? Answer by writing an equation, using structural formulas or skeletal formulas for each of the following: a) the reaction of aqueous HCI with the magnesium salt in question 2. b) the reaction of aqueous HCl with the unreacted magnesium turnings. 5. If you added too much HCI and your Grignard product should undergo SNI or Sx2 reaction to have any evidence that this side product may be present? Explain fully. 6. If the reaction had undergone elimination, what are the structure and physical properties of this side product? Do you have any evidence that this side product may be present? Explain fully.
