D (C6H5)3PCH₂C6H5Cr, NaOH CH₂Cl₂ This is the Wittig reaction (synthesis to make E and Z stilbenes) This is for the Wittig Lab of Organic Chemistry 2. Please answer to all 3 questions with explanations as simple and specific and possible to understand. 1. What happens when NaOH is added to the reaction mixture? Draw the species formed and any reasonable resonance form(s). 10 pts 2. Once the reaction mixture is added to a test tube and dichloromethane (DCM) is added, why is a sodium bisulfite wash performed? (10 pts) After the bisulfite is added, what is the predominate solute in the organic layer and aqueous layer? Draw a sketch of the test tube showing the two layers and the solutes. (10 pts)
