When a ketone reacts with a Grignard reagent, a reaction
known as a Grignard reaction occurs. The reaction proceeds through a
nucleophilic addition mechanism, resulting in the formation of an alcohol.
The Grignard reagent, which is an organomagnesium compound,
acts as a strong nucleophile and attacks the carbonyl carbon of the ketone. The
resulting intermediate is an alkoxide ion, which then protonates to form the
corresponding alcohol.
