If you were to compare the rates of acylation of ferrocene and acylation of benzene, the ferrocene would react much faster. What does this tell you about the electron density of the cyclopentadienyl rings on the ferrocene? (The best answers will likely use resonance structures to show how the electron density is distributed in both ferrocene and benzene.)

If you were to have performed a TLC analysis of ferrocene and
acetylferrocenesamples using pure diethyl ether (rather than as the
more polar solvent in a 1:1 mixture with the less polar petroleum
ether), which of the two spots would have a greater Rf? Explain
briefly.

CHROMATOGRAPHY
In running a TLC analysis of ferrocene and acetylferrocene, the
two substances were analyzed on a TLC plate in 3 different solvents
(1:1 petroleum ether/diethylether, and petroleum ether and
diethylether, respectively). What would be some clues that the
samples of ferrocene and acetylferrocene being used in this
analysis were impure?

1. The possible components of your mixture are unreacted
ferrocene and the substituted ferrocene product(s) of your
reaction, which should travel the farthest up the TLC plate
(highest Rf) and why?
2. Which should have a higher Rf value: the mono-substituted
ferrocene or the di-substituted ferrocene?
3. In the column chromatography portion of your experiment next
week, you use different solvents or solvent mixtures to elute the

You are quantitating benzene using isopropyl-benzene as an
internal standard. During the first run, you add 100.0 microliters
of 500. microgram/mL benzene and 100.0 microliters of 500.
microgram/mL isopropylbenzene to a vial and dilute to 1.000mL to
prepare a solution that has a final concentration of 50.0
micrograms/mL of benzene and isopropylbenzene. The peak area
measured by GC-MS corresponds to 1225 and 1775, respectively.
Taking an unknown sample of a solution containing benzene with a
volume of 100.0 microliters, you...

Two liquid streams are flowing at constant rates into a blender.
One is benzene, which flows at a measured rate of 20.0L/min, and
the other is toluene. The blended mixture enters a storage tank
(inner diameter = 5.5m) equipped with a sight gauge. During an
interval in which no liquid leaves the storage tank, the liquid
level in the tank is observed to increase by 0.15 meters over a
one-hour period. Calculate the flow rate of toluene into the
blender...

Melting point of ferrocene = 171.5-172.6 degrees Celcius
Literature melting point of ferrocene = 172-174 degrees
Celcius
Melting point of acetylferrocene = 78.9-83.2 degrees Celcius
Literature melting point = 81-81 degrees Celcius
What do these melting points indicate about the purity and
identity of the ferrocene and acetylferrocene samples?
