CAN SOMONE PLEASE HELP. above is a picture of two TLC plates
with spots on them. could somone PLEASE PLEASE PLEASE help me get
their measurmentS (in milimeters) and help me calculate their Rf
values!!! I promise to rate u good if you could help!!! Im so
confused!!! THANK U SM

Attached is the lab experiment. Here are the questions I need
help with:
1. What is the purpose of each of the following steps in this
experiment?
a. Adding solid NaCl to the reaction mixture
b. Repeated washings with water, sat'd NAHCO3, and brine
c. the pipet column chromatography
2. Which compound, cyclohexanol or cyclohexanone will have a
higher Rf on a TLC plate?
3. What is the advantage of using sodium hypochlorite as an
oxidant over CrO3 or Na2Cr2O7...
what is the prediction of the unknown amino acids mixture
based on the strip from thin layer chromatography sheet?
The unknown mixtures can be ala plus asp, ala plus asp plus
lys, lys plus asp or ala plus lys.

1 - Provide a balanced equation for this reaction
2 - Provide a mechanism for the transformation of cyclohexanol
into cyclohexanone
3 - Provide a flow chart for the workup procedure for isolating
cyclohexane from all the by-products, making sure to note in which
layer you expect to find your product in each extraction.
4 - Provide the theoretical yield of cyclohexane in this
experiment.

Multistep Synthesis Preparation of 4,4-Diphenyl-3-buten-2-one! This experiment illustrates se multistep synthesis, in which the the next. This process is very common iment illustrates several important concepts of organic synthesis. It is a synthesis, in which the product of one reaction becomes the starting material of This process is very common in industry and research, and demands careful to vields and techniques. The experiment...
2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...
Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
