Help with theoretical and percent yield
Theoretical yield
# of moles reactant x (mole of product / mole reactant)
2.038g (E)-stilbene x (1 mole E-Stilbene/180.2488 g E-Stilbene) = 0.01131 moles E-Stilbene
0.01131 moles E-Stilbene x (340.0568g 1,2-Dibromo-1,2-diphenylethane /1 mole product) = 3.845g
Percent yield = (expected yield / theoretical yield) x 100 %
=(actual product/theoretical yield) x 100 %
what would be the limiting reactant
Bromination of Stilbene lab would my product be pure and why based on the following data Melting point Crude: 236.4 – 240.2 ℃ Product 238.7-239.9 ℃ Lit melting point: 235-241℃
