This is a section that is going to be part of an upcoming labquiz. The section involves an experiment we have covered this semester. In the experiment we reacted trans-cinnamaldehyde with benzyltriphenylphosphonium chloride in a "wittig" reaction toform (E,E)-1,4-diphenyl-1,3-butadiene. The experimentinvolved us mixing trans-cinnamaldehyde andbenzyltriphenylphosphonium chloride and DCM. When those weremixed we added 50% NaOH once we started our magnetic stirbar. When all was said and done(E,E)-1,4-diphenyl-1,3-butadiene was formed.
Here are some questions that I didn't know the answers to. Thank you to anyone that helps me. I Will Rate Lifesaver!

1. Assume you began with cis-cinnamaldehyde rather than the transform, which isomeric forms might you obtain?

2. Using E,Z nomenclature, how would you name an isomer containing alternating double bonds in the order of cis, cis, trans,trans, cis?

3. Since carbon is not ordinarily nucleophilic, what stabilizes the nucleophilic carbon in aldol and wittig types of reactions?

4. What function does sodium sulfate serve in the experiment?

5. During extraction using a separatory funnel containing dichloromethane, water, and hexande; which should be the middlelayer?

6. The reaction of benzyl chloride with triphenylphosphine is what type of reaction?

7. Calculate the volume of 20.1 mmol of benzyl chloride.
