Question
Synthesis of triphenylmethanol from Bromobenzene, Mg and Methlybenzenoate experiment. 1. What would happen to the yield of product if you used regular lab grade ether instead of anhydrous ether to dissolve the ester in step 4 above? Write an equation illustrating the process. 2. write the equations for the reaction of Hclag with the magnesium salt of the alcohol you made and with the unreacted magnesium turnings. 3. What is to formula of the solid precipitate, which may form after the ester has been added to the Grignard reagent? 4. Propose a mechanism for this experiment. 5. Explain how triphenylmethanol could be prepared from bromobenzene and ethylbenzoate (need to suggest a possible mechanism.)Explanation / Answer
this reaction involved formation of a grignard reagent. This reagent reatec with water to form an alkane. Thats why anhydrous ether has to be used.
