Answer 1

Br Br Molecular Weight: 180.25 Molecular Weight: 340.05 Theoretical yield 180.25 g of stilbene gives 340.05 g of dibromo-compound then 0.058 g of stilbene gives X g of dibromo-compound 340.05 g x 0.058 g X g of dibromo-compound 180.25 g X g of dibromo-compound 0.109 g Percent yield 0.109 g is 100% yield then 0.063 g X % yield 0.063 g x 100 X% yield 0.109 g X% yield 57.79%
