You 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. WebRoute C-3 suggests an oxidation of a secondary alcohol, which could be obtained through a Grignard-type reaction. Cleavage d: This implies a Micheal addition.
