First, you used the 1:1 diethyl ether/petroleum ether mixture; then switches to pure petroleum ether after the first colored band is collected.

a) Which (ferrocene or acetylferrocene) would elute first? Explain
b) Does it take more, less, or about the same amount of this “wrong solvent” to elute the ferrocene (as compared to using pure petroleum ether as instructed)?

Ethyl acetate is another common organic solvent used in the type of TLC experiment you performed: it has a higher molecular weight and boiling point than either petroleum ether or diethyl ether, and is more polar than them as well. If ethyl acetate had been used as the mobile phase for a TLC analysis of F and AF, how would their Rf values compare to those found using the 1:1 solvent mixture you used? That is, predict how the behavior...

a student loaded their mixture of acetylferrocene and diacetylferrocene onto column using 5ml of dichloromethane as the loading solvent. They used about 7 g of SiO2 as the stationary phase. The student then eluted the column using petroleum ether. After collecting 8 fractions, the student analyzed them by TLC to find all of the compounds came off in the first two fractions, with no separation. Where did the student go wrong and what should they do differently when they try...

1. If you load the mixture of compounds using more than a "minimal amount of CH2Cl2", what will happen to your separation? A. The seperation will be poor since CH2Cl2 is a less polar solvent than petroleum ether. B. The seperation will be improved since CH2Cl2 is a more polar solvent than petroleum ether C. The seperation will be improved since CH2Cl2 is a less polar solvent than petroleum ehter D. The seperation will be poor since CH2Cl2 is a...

1. a) draw the structure of the product you would have isolated if you had used NaBD4 in D2O in this experiment, write a mechanism explaining the result. (b) give the product structure for the same reaction using NaBD4 in H2O. Assume that there is no hydrogen exchange between NaBD4 and the solvent. Not sure if this is relevant to the question but here is the procedure used: Dissolve 3.8g of vanillin in 12mL of ethanol in a small beaker...

Provide your responses to each discussion: (Responses were analytical and demonstrated original thought.) Discussion:1 Better fuel economy is the primary motive behind hybridization. The electric cars rely on electricity, then less gasoline or diesel. When the first hybrid cars like Toyota Prius and Honda Insight went on sale in Japan, most automakers felt electric cars couldn’t travel very far on a full charge. In the recent years, electric cars have improved significantly and the sales have been increased too. From...
