**Question 4:** Identify reagents that you would use to the following via a Wittig reaction. Keep in mind the stereochemistry. **Chemical Structure:** - The diagram shows a molecule with two phenyl groups (Ph) connected by a double bond, indicating a stilbene structure. The double bond indicates possible E/Z isomerism. **Explanation:** To synthesize this molecule using a Wittig reaction, one would typically start with a suitable carbonyl compound and a phosphonium ylide. The phenyl groups suggest the starting materials could be: - A benzaldehyde derivative for the carbonyl compound. - A phosphonium ylide with a phenyl group for the corresponding reaction partner. The stereochemistry consideration implies that the reaction conditions or choice of ylide may be adjusted to control whether an E or Z isomer predominates in the product.
