1. Compact discs are produced from polycarbonate polymer. Bisphenol-A (CgHO2) is one of two major raw materials of polycarbonates. Bisphenol-A is synthesized from toluene (C,H,O) and acetone (C,H,O) by using the following reaction: 2C,H,0 + C,H,0 → CHO2 + H,0 If 6.6 moles of toluene is mixed with 4.0 moles of acetone, a)What is the limiting reactant? b)What is the excess reactant? c)What is the theoretical yield, in g, for bisphenol-A? d)What is the percent yield if actually 643.7 g bisphenol-A is produced?

l ECONET LTE 14:13 @ 70% AA A bbb4.ciu.edu.tr CHEM 110 CONT.. O 35:06 Edith Ahaka ASSIGNMENT 1. Compact discs are produced from polycarbonate polymer. Bisphenol-A (C,5H16O2) is one of two major raw materials of polycarbonates. Bisphenol-A is synthesized from toluene (C,H,O) and acetone (C,H,O) by using the following reaction: 20,H,0 + C,H,0 –→ Cı5H1,02 + H,O If 6.6 moles of toluene is mixed with 4.0 moles of acetone, a)What is the limiting reactant? b)What is the excess reactant? c)What is the theoretical yield, in g, for bisphenol-A? d)What is the percent yield if actually 643.7 g bisphenol-A is produced? e)How many grams of the excess reactant remains unreacted? (Mcso = 94.1 g/mol, MeKo = 58.1 g/mol, MCISH602 = 228.3 g/mol) 2. n-Butyl lithium is an important raw material in the production of synthetic rubber SBR. n-Butyl lithium (C,H,Li) is synthesized according to the following equation: 2Li + C,H,Br - C,H,Li + LiBr In an experiment a technician mixed 150.0 g Li with 150.0 g C,H,Br. (a) Which of the two reactants is the limiting reagent? (b) Calculate the mass of C,H,Li formed. (c) How much excess reagent (in grams) is left at the end of the reaction? (Assume that %yield - 100%) Mu = 6.94 g/mol, McaH9Br = 137.02 g/mol, McaH9li = 64.1 g/mol) 31
