6. Explain why you switched solvents while running the column. To answer this question, answer parts (a) and (b) (a) What would have happened if you used hexanes for the entire duration of the column? Answer in ONE SENTENCE. (b) If you had used 1:1 hexane/ethyl acetate right when you started running the column, both compounds would have moved down the column rapidly and poor separation would have been achieved. In this scenario, one compound would still move down the column slightly faster than the other. What compound would have come out of the column first? Ferrocene Acetylferrocene Looking at your TLC plate, were you able to efficiently separate ferrocene and acetylferrocene? Explain how you know (be specific, what is the one thing that you need to observe to determine if separation was achieved). 7. es

Explanation / Answer

Answer a) Both of the compounds would have not come out of column as the polarity of the hexane solvent is not enough to move the compounds down the column.

b) Ferrocene would have come out first as it is slightly less polar than acetyl ferrocene. Acetyl ferrocene will have hydrogen bonding with the silica (SiO2) in the TLC plate hence slowing down.

You have to look the eluted TLC plate in which only one product (acetyl ferrocene) is remaining out of the two.
