Infrared The top layer (ether layer) contained the product while the bottom aqueous layer contained the magnesium bromide layer as the by-product. When analyzing the signals in the 'H NMR, be sure to include all appropriate information. The aim of this experiment was to prepared Grignard reagent (phenylmagnesium bromide) from bromobenzene and magnesium to use the reagent prepared to synthesise a tertiary alcohol (triphenylmethanol) by reacting reagent and ester (methyl benzoate) and the product formed is analyse by infrared spectroscopy (IR) melting point thin layer chromatography (TLC) gas chromatography mass spectrum (GCMS) and finally Nuclear Magnetic Resonance spectroscopy. Preparation Of Triphenylmethanol Objectives 1. Especially useful are p. A19 and A20. 8 June. The final product was purified and characterized using TLC and IR spectroscopy. In this case, the electrons on the negatively charged oxygen atom are used to reform the carbonyl pi bond, thereby forcing the C-N or C-O bond of the ester, amide, or anhydride to detach as a leaving group generating a ketone intermediate. - 1585 cm ^-1 and 1500 - 1400 cm^-1.
