Calculate the percent yield if you start with 0.18 mL trans-cinnamaldeyde and 0.617 g benzyltriphenylphosphonium chloride in 2 mL 10 N NaOH and isolate 0.206 g (E,E)-1,4-diphenyl-1,3-butadiene. Show ALL your calculations!
(Hint: first you need to compare the moles of the substrates to know which substrate is the limited reagent. Then you calculate the percent yield by comparing the moles of the product with the theoretical yield (moles of the limited reagent).)
