The Rf value on a TLC is getting higher, if the eluent is changed to more polar

Question

The Rf value on a TLC is getting higher, if the eluent is changed to more polar one less polar one lower temperature one higher temperature one A fresh TLC plate is spotted with compounds A, B, and C, but this time the solvent is nonpolar hexane. How will this affect the Rf of compound A? the Rf of A in the new solvent will be the same as in methylene chloride the Rf of A in the new solvent will be greater than that in methylene chloride the Rf of A in the new solvent will be less than that in methylene chloride the Rf of A in the new solvent will be changed based on The TLC plate is prepared by drawing a light line 1 cm from the bottom of the plate to mark where the samples should be spotted. This line is drawn with: pencil black pen a blue pen a red pen A beaker will be used as a "developing jar" in this experiment. When the TLC plate is set in this beaker, the solvent in the beaker must be: above the pencil line used to guide the spotting of samples. deep enough to cover the entire TLC plate. enough to come about halfway up the TLC plate. the pencil line used to guide the spotting of samples.

Explanation / Answer

13. Answer: Rf = 8/10

                = 0.8

14. Answer: less polar one
