Suppose your TLC plate looks like the image below (ran 1:1 ratio ethyl acetate/hexane). What is the Rf value of the red compound (lower compound, 1 cm from the baseline)? How could the solvent combination be varied to lower the Rf value of the red product? How can we change the eluent composition to improve the separation of the two products on column chromatography? Solvent line 6.8 cm 5.1 cm X--X-- Base line SM Co P rf value choices: 0.1, 0.15, 0.25, 0.3, 0.35, 1.15 how could solvent combination be varied choices: increase ratio of hexane or decrease ratio of hexane how can we change eluent composition choices: start with more polar eluent or start with less polar eluent

In an experiment of Reverse Phase chromatography using C-18 stationary phase and a mixture of methanol/ethyl acetate/acetic acid, a researcher tried to separate the 3 compounds shown below. Which compound would have the lowest Rf and which the highest Rf in this experiment? Explain your answer and show any relevant structures.
During a Thin layer chromatography (TLC) analysis of crystallized napthalene, what would the effect of adding a higher proportion of ethyl acetate to the developing solvent on the compound’s Rf values?
How can molecules with the same charge at varying amounts be separated by Ion exchange chromatography?
A peak with a retention time of 10 minutes has a width at half-height of 7.6 s neighboring peak is eluted 15 s later with W1⁄2 = 7.5 s. (a) Find out the resolution for these two components. (b) Is this resolution value good for quantitative analysis, why?
a. Say you are trying to separate two compounds by column chromatography. You run a column and collect the eluent in five fractions. You analyze each fraction by TLC on the same plate (shown below). Based on the TLC plate, how effective was your separation? Consider the purity of each fraction. - - - - - - - - ----| 1 2 3 4 5
In the table below, record the color that you observe for each spot or component of each spot after the run is completed. For the retention factor, R₁, write in the numerator (top) the number of mm that the spot has moved and in the denominator (bottom) the number of mm that the solvent has moved from the point where the samples were 'spotted. Calculate the Rf vale for each spot or component of each spot. Im having a difficult time finding the Retention Factor for M&Ms by using Salt water and seeing how much each color moves Instructions Coffee filters usually are round, but it's easier to compare your results if the paper is rectangular. So, your first task is to cut the coffee filter into a rectangle. Measure and cut a 2-3/4" by 7" strip from the middle of a coffee filter. This is easily done by folding the filter in half (to make a half-circle) and then folding the half-circle into thirds. Cut along the 13-fold lines and trim the ends to make a rectangle. 2.

What is stationary phase used is liquid chromatography? What compounds does it bind best and why?
One of the main differences between TLC and column chromatography is the direction in which the mobile phase moves. Group of answer choices True False
