Calculate the percent yield if you start with 0.220 mL trans-cinnamaldeyde and 0.6643 g benzyltriphenylphosphonium chloride in 1.5 mL 10 N NaOH and isolate 0.2137 g 1,4- diphenyl-1,3-butadiene. Show ALL your calculations! (3 points) (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).

what would be the percent yield if the final weight of my product
is 0.1357g this is a green chemistry wittig reaction to produce
1,4-diphenyl-1,3-butadiene from benzyltriphenylphosphonium chloride
and trans- cinnamaledyde using sodium hydroxide as the base
You will be using a Green Chemistry Wittig reaction (NOT Wittig-Horner Emmons reaction) to produce 1,4-diphenyl-1,3-butadiene starting with benzyltriphenylphosphonium chloride and trans- cinnamaledyde using sodium hydroxide as the base. This reaction is considered a "green" reaction, because an aqueous solution will be used...
