Question

Based on the lab PreReading, which of the following statements best describes substrate mobility on a TLC plate? Select one: a. Polar substrates are retained better by a polar solid phase, and thus typically have lower RF values than non-polar compounds. b. Polar substrates are better solubilized by a polar mobile phase, and thus typically have higher RF values than non-polar compounds. c. Polar substrates are retained better by a polar solid phase, and thus typically have higher RF values than non-polar compounds. d. Non-polar substrates are better solubilized by a non-polar mobile phase, and thus typically have lower RF values than polar compounds.

Explanation / Answer

c. Polar substrates are retained better by a polar solid phase, and thus typically have higher RF values than non-polar compounds.

this is the correct statement which describes the TLC analysis in a better way. Nonpolar compounds always have greater Rf than polar compounds.
