from measurements on FTIR instruments or in other chemical IR Spectrum. The reaction mechanism for the reaction between alkyl halides and Grignard reagent is similar to that involving a proton and the Grignard reagent. A new bond forms between the nucleophilic carbon of the Grignard reagent and electrophilic carbon of the alkyl halide.
