Transcribed Image Text:5. Summarize your conclusions from the TLC simulator. Circle the correct answer in each description about TLC
separation of organic compounds on silica gel plates.
a) A more polar compound has a lower/higher retention factor.
b) A less polar compound has a lower/higher retention factor.
c) A more polar solvent causes a lower/higher retention factor.
d) A less polar solvent causes a lower/higher retention factor.
e) To increase the retention factor of a spot, you should add more ethyl acetate/hexane.
Expert Solution
Step 1
A) A more polar compound has a lower retention factor. Because the silica plate is polar. As polar likes polar. So it does not move forward.
B) A less polar compound has a higher retention factor because non-polar compounds does not form any interaction with silica. So they move with solvent.
C) A more polar solvent causes a higher retention factor because the compound get higher solubilized in polar solvent and move with polar solvent.
