The TLC shown above, similar to the silica (SiO₂) TLC plates you used in lab, w developed in a solvent system that comprised of hexanes (5mL) + ethyl acetate 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 th product spot will remain unchanged. ↓ The Rf 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. Question 6 (6 point)

Which of the following correctly describes the change in Rf values if the developing solvent was changed to Hexanes (3mL) + ethyl acetate (7mL) ?

0.0 cm. product 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. Question 6 (6 points)
