Write a mechanism for this reaction below.

Why is a strong acid (like HCI) used in a Grignard reaction? O 1) A strong acid is used in the Grignar reaction in order to protonate the carbonyl in order to make a better leaving group, OH. Once teh OH leaves, the alcohol group is reformed due to water. A stable tetrahedral intermediate with a negatively charged oxygen forms O 2) that does not possess a leaving group. This intermediate will exist until a proton source from the strong acid protonates the negatively charged oxygen, affording the neutral alcohol product. 3) The use of a strong acid is not necessary. It is simply recommended as it increases the yield produced in the reaction. 4) The use of a strong acid is necessary for the formation of a Grignard reagent. Without a strong acid, the organomagnesium compound cannot be formed.
