How many g of anthracene would you need to react with 9.8 g of maleic anhydride in a Diels-Alder reaction? (Assume a 1:1 molar ration of anthracene to maleic anhydride.)
2 - If you started lab using 0.221 g of anthracene and 0.652 g of maleic anhydride, and obtained 0.182 g of product, what is the percent yield?
Homework Answers
