7) Summary/Post Lab Questions
a. Discuss your results
i. Make sure to identify each spot in your TLC plate. Which one
corresponds to ferrocene? To monosubstituted product? To disubstituted
product?
ii. Based on your TLC results, did the reaction go to 100% completion?
iii. Does UV of your TLC shows both products? If not, why don’t you see the
disubstituted product?
iv. If you did not obtain ferrocene after purification by column
chromatography, why might have been the reason?
v. If you did not obtain the monosubstituted product after purification by
column chromatography, why might have been the reason?
vi. If you did not obtain the disubstituted product after purification by
column chromatography, why might have been the reason?
vii. Explain your melting points and how they help you identify the products
you obtained
b. Post-Lab Question #2 only
