Question

3. (a) Why must anhydrous diethyl ether be used in this reaction?

-Grignard reagents react immediately with any water present in the reaction mixture

-Magnesium reacts vigorously with any water present in the reaction mixture

-The reagents used in this reaction are only soluble in anhydrous diethyl ether

-The Grignard reagent reacts very slowly if there is any water present in the reaction mixture

(b) Extraction is a common separation technique that is used to help separate reaction products out of reaction mixtures which contain unreacted reagents and bi-products. During this experiment you will extract the reaction mixture with 5% aqueous sodium hydroxide.

What is the outcome of this step?

-Formation the sodium salt of benzoic acid

-Removal of magnesium salts

-Generation the Grignard reagent

-Protonation of benzoic acid

Explanation / Answer

3(a) grignard reagent readily react with water and form corresponding alkane (b) if NaOH is used then the remaining grignard reagent will remove
