WebOnce the Grignard reagent has formed, the carbonyl containing compound is added to the solution. A magnesium alkoxide is produced from the ensuing reaction: In the experiment that you will perform, bromobenzene is the alkyl bromide used to make the Grignard reagent, and the carbonyl containing compound is methyl benzoate, an ester. In this WebYou have to exclude water from this reaction again, because the Grignard reagent will react with it. So in the first step, you want it to react with your carbonyl. And the second step, once it's reacted with the carbonyl, it's OK to add water in the form of H3O plus. And this is going to form our alcohol.
