Consider caffeine and acetaminophen:
What structural features (functional groups) cause one to move farther than the other on the TLC plate?
Homework Answers
Caffeine
From the structure of both the compunds it is clear that caffeine do not have hydroxy group and acetaminophen have the hydroxy group this is the reason which cause one to move farther than the other on the TLC plate.

The three compounds below were spotted on a TLC plate and developed to give the TLC plate shown. Which compound corresponds to which spot? Calculate the Rf value for spot B in the TLC plate shown above. When using polarity to determine the relative rates at which organic compounds travel up the TLC plate, we are considering compounds of similar molecular weight. It should also be noted that Rf values...
