WebApr 9, 2024 · Note: Ketone reacts with 1 equivalent of Grignard reagent while ester reacts with 2 equivalents of a Grignard reagent to give tertiary alcohol. Since formaldehyde does not contain an alkyl group it is the only aldehyde that gives primary alcohol on reaction with the Grignard reagent. While other aldehydes give secondary alcohol. WebGrignard reagents are prepared by reacting either alkyl or alkenyl halides (chloro, bromo, or iodo, never fluoro) with magnesium metal. The reaction occurs on the surface of the Mg and involves single‐ electron transfers, radical ions, surface‐bound species, and possibly free radicals as well.
