Homework Answers
an important factor in determining cis or trans geometry depends on the substituent attached to phosphonium ylide. When an electron releasing group is attached to ylide it will lead to the cis product or Z-selective product. when the electron-withdrawing group is present it will lead to trans product or E-product.

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...

Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.
