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?

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.

Briefly explain why is a solid liquid extraction used prior to running a TLC analysis on an unknown compound and why ethanol is a chosen solvent. Also explain what the mobile phase for TLC is and why it is chosen. If something did not go as planned during the experiment, explain what can go wrong.

Explain how liquids can be analyzed by gas chromatography.

When 2-propanol was used as the develop- ing solvent, two substances moved with the solvent front (Rf = 1) during TLC analysis on a silica gel plate.

1. When 2-propanol was used as the develop- ing solvent, two substances moved with the solvent front (Rf = 1) during TLC analysis on a silica gel plate. Can you conclude that they are identical? If not, what additional experiment(s) would you perform? 2.The Rf value of compound A is 0.34 when a TLC plate is developed in hexane and 0.44 when the plate is developed in diethyl ether. Compound B has an Rf value of 0.42 in hexane...

In TLC, the polarity of the different compounds to be analyzed is highly critical. Which one of the following statements is true? (Check all that apply) 1 The less polar components of the mixture to be analyzed will be less attracted to the stationary phase and therefore move further up the plate. 2. Any solvent mixture can be used to separate any compound mixture with TLC. 3. The more polar components of the unknown mixture move faster up the plate...

Thin Layer Chromatography 1. After running the first plate, the spot was not observed. Provide two possible reasons (not including operator error) as to why? 2. What other technique could be used to determine if a reaction was complete? Explain to a peer, how you would do this in lab. 3. Why might TLC not be the best technique to determine the identity of a compound?

An unknown mixture was analyzed using TLC on a silica gel plate and developed in 1:6 ethyl acetate:hexane, and gave 2 spots with Rf values of 0.6 and 0.5 respectively. 1)Would this be considered a good separation between the two? Briefly explain. 2)Which spot represents the more polar compound(s)? 3)Can you say for sure how many compounds are contained in the mixture? If so, how many are there? Briefly explain. 4)If not, what further conditions might be performed to determine...
