The TLC shown above, similar to the silica (SiO₂) TLC plates you used in lab, was
developed in a solvent system that comprised of hexanes (5mL) + ethyl acetate (5
mL). Which of the following correctly describes the change in Revalues if the
developing solvent was changed to hexanes (3 mL) + ethyl acetate (7 mL)?
The Rf value of the starting material spot will increase, but the Rf value for the
product spot will remain unchanged.
The Re values for all spots will decrease
The Re values for all spots will increase.
The Rf values for both spots are not expected to change because the total
volume of the solvent is identical in both developing conditions.
The Rf for the starting material spot will remain unchanged, but the Rf value for
the product spot will increase.
