Name: Quiz 5 1. Suppose you took a TLC and observed a spot that had an R f = 0.05, but wanted the R f to be approximately 0.3. How would you increase the R f if you encountered this situation and continued to use the same normal phase silica gel TLC plates? (Hint: Think about the mobile phase) 2. O OH Above are TLC's of the starting material and product of today's reaction. How should a 3-lane TLC look after 100% consumption of the starting material? Draw your answer on the TLC plate below. 3. What spectroscopic method would be the best to monitor this reaction?
