Question

Why is part D only 0.2mol? Why can't 0.4mol be made? 

The synthesis of phenylmagnesium bromide and its reaction with methyl benzoate gives triphenylmethanol and biphenyl as major products. A student started with 10.8 g Mg, 62.8 g bromobenzene, 21.8 g methyl benzoate and got 30.0 g of triphenylmethanol and 2 g of biphenyl as products. (Molecular or g atomic weights: Mg, 24.1; bromobenzene, 157.0; methyl benzoate, 136.2; biphenyl, 154.1; triphenylmethanol, 260.3.) Be sure to show your work to answer the following questions. Ryn 1: PhBrt mg → Phmg Br Rxn 2: 2 Ph Mg Br + Ph-eo-0elta (a) What was the limiting reagent in the formation of triphenylmethanol? > Phze-o Cafter hydro bpo) Here 0.45 mol Mg, 0.40 mol Ph Br, ko.16 mol melyl benzote used.
