Question

In this experiment, you will analyze your sample by TLC by spotting pure benzophenone and your product and eluting with 5:1 hexanes/ethyl acetate. Choose the statement that BEST describes what you should observe for a successful experiment.

A) The benzophenone in the standard and reaction samples should travel the farthest and will have the same Rf value. No unreacted benzhydrol should be observed at a lower Rf value.

B) The benzophenone in the standard and reaction samples should travel the least and will have the same Rf value. No unreacted benzhydrol should be observed at a higher Rf value.

C) The benzophenone in the standard and reaction samples should travel the farthest and will have the same Rf value. Unreacted benzhydrol should be observed at a lower Rf value.

D) The benzophenone in the standard and reaction samples should travel the farthest and will have the different Rf values. No unreacted benzhydrol should be observed at a lower Rf value.

Explanation / Answer

Option A best describes for the successful experiment because,

Ina media of 20% ethyl acetate/hexane, the benzophenone will move farther with high Rf value because Benzophenone is no-polar in nature and Benzhydrol should be at lower Rf value as it is polar molecule therefore will not rise in this media.

And for a successful experiment, there should not be any Unreacted Benzhydrol left in the experiment.

The benzophenone in the standard and reaction samples should have the same Rf value.
