In this experiment‚ the production of a Grignard reagent (phenylmagnesium bromide) was performed from a bromobenzene reactant combined with magnesium and ether. Phenylmagnesium bromide was then transformed into a tertiary alcohol called triphenylmethanol‚ through addition of another compound called benzophenone‚ as well as additional ether. The end product of triphenylmethanol was analyzed via NMR and IR. Figure 1: Preparation of the Grignard agent by combining bromobenzene with magnesium and ether

carbonate. The resulting products were solid calcium carbonate and aqueous sodium nitrate (equation 1). To calculate the theoretical yield‚ the moles of sodium carbonate and calcium nitrate were calculated to find the limiting reagent. Then the moles of the limiting reagent (calcium nitrate) were used in ratio with the precipitate ( 1:1)‚ calcium carbonate‚ to find how many moles of the solid were produced‚ then to conclude the mass of the precipitate (equation 2). The percent yield was calculated
