ATTN: answers to the below questions are due at the start of your lab period; these answers should be part of your pre-lab write-up
Homework assignments
1. How is the electrophile in this reaction generated in this reaction? Show an appropriate chemical equation.
2. Which organometallic compounds are present in the reaction mixture after the reaction? Draw their structures.
3. Flash chromatography is used in this experiment. First petroleum ether is used as eluent, later a mixture of petroleum ether with ~10% ethyl acetate. What do you expect to observe during this step of the purification? What would happen if the student decide to use pure ethyl acetate instead?
4. The reaction mixture is poured into a sodium acetate solution. Why? Show pertinent equations.
5. How do you explain the orange-red color of the ferrocene and acetyl ferrocene?
