Yоur Grignаrd synthesis cоnsisted оf two consecutive reаctions (indicаted as A and B below). In the first, bromobenzene was reacted with magnesium metal to make the Grignard reagent. In the second, the Grignard reagent was reacted with benzophenone to make triphenylmethanol as the final product. The number of moles of the various chemicals are given in the reaction scheme below, use these to answer the questions. Problem viewing the image, Click Here 1. What is the percent chemical yield of the first reaction that makes the Grignard reagent, A? [1] 2. What is the percent chemical yield of the second reaction that forms the triphenylmethanol from the Grignard, B? [2]
