Should the order of spots of molecules on the TLC be different when two different eluent solvents are used? Explain your answer?

Should the TLC spot of a compound move higher or lower or stay the same when compared to in a less polar eluent solvent system when a more polar eluent solvent system is used?

A TLC plate showed two spots with Rf values of 0.25 and 0.26. The plate was removed from the developing chamber, the residual solvent was allowed to evaporate from the plate, and then the plate was returned to the developing chamber. What would you expect to see after the second development was complete?

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...

The number of coins that Jake spots when walking to work can be modeled as a Poisson process with unit rate of 3/half an hour. Suppose it takes Jake half an hour each day to walk to work, and half an hour to walk back. Each coin is equally likely to be a penny, a nickel, a dime, or a quarter. Jake ignores the pennies but picks up the other coins. (a) Find the expected amount of money that Jake...

In a certain species of moth, there are two variations in the number of black spots on the wings, either 2 or 4, which appear to be the result of a single gene. Scientists hypothesize that 4 spots is dominant to two spots. They cross two individuals that appear to be heterozygous for this trait and 140 offspring are produced. If 4 spots is in fact dominant: 1. how many would be expected to display 4 spots? 2. how many would...
