What is the detailed mechanism of the Grignard reaction?

Question

Accepted Answer

The Grignard reaction involves the addition of an organomagnesium compound to a carbonyl compound, resulting in the formation of a new carbon-carbon bond.

Grignard reagents are highly reactive organomagnesium compounds that are prepared by reacting an alkyl or aryl halide with magnesium metal in anhydrous ether.
The Grignard reagent acts as a nucleophile, attacking the electrophilic carbon of the carbonyl group in the substrate.
After the addition of the Grignard reagent, the resulting alkoxide intermediate is protonated to yield the final alcohol product.
The reaction is typically carried out in dry conditions to prevent the Grignard reagent from reacting with water instead of the carbonyl compound.
