Answer :
Final answer:
In the hydrolysis step, excess Grignard reagent reacts with water to produce the corresponding hydrocarbon and magnesium hydroxide.
Explanation:
In the hydrolysis step of a Grignard reaction, any excess Grignard reagent reacts with water to form the corresponding hydrocarbon and a magnesium hydroxide by-product. Specifically, CH3MgI would react with water to yield methane (CH4) and magnesium hydroxide (Mg(OH)2). In organic synthesis, this hydrolysis step is crucial to finalize the formation of the intended product, such as a ketone or an alcohol, from the initial Grignard addition reaction.
