The reaction is
Trans- 1,2-dibenzoyl ethylene …………………………….> Cis- 1,2-dibenzoyl ethylene
Mol. Wt. : 236.26 g/mol 236.26 g/mol
From the above transformation
236.26 g of trans-1,2-dibenzoyl ethylene produces cis-1,2-dibenzoyl ethylene = 236.26 g
0.192 g of trans-1,2-dibenzoyl ethylene produces cis-1,2-dibenzoyl ethylene = 0.192 g
Theoretical yield = 0.192 g
Actual yield = 0.082 g
% yield = (Actual yield/Theoretical yield) x 100% = 42.71%

1) When you measured out one mL of the trans-1,2-dibenzoylethylene in ethyl acetate solution it had a mass of 0.890 grams. (0.050 g of yellow solid and rest of it is Ethyl acetate). The forerun of ethyl acetate had a mass of 0.075g and the rest of the ethyl acetate collected had a mass of 0.253 g. The trans-1,2-dibenzoylethylene had a mass of 0.046 g. What is the percent recovery of each of the materials?

We learned that to create vicinal diols from alkenes, the cis-1,2-diol or trans-1,2 diol required very different reagents. This isn't always the case and one notable reaction that defies this convention is the Prévost reaction! (4 points) To make the cis-diol, we typically use osmium tetroxide (catalytic amounts!). What other reagent combination would work for this particular transformation? a. OH OH (rac b. (4 points) To make the trans-diol, what reagent combination would be employed? ?? 1F2 OH (4 points)...

You are monitoring the decay of 13-cis-retinal to all-trans-retinal. Initially, your sample contains 100% 13-cis-retinal. After 5 minutes, you see that 55% of your sample has converted to all-trans-retinal. Assume that the all-trans-retinal cannot convert back to 13-cis-retinal. a. What is the rate constant that describes the transformation of 13-cis-retinal to all-transretinal? b. How long will it take for 95% of the sample to be converted to all-trans-retinal?
