Question
You perform the Aldol reaction between A and B below to make C.
After about an hour of stirring, you take a TLC of the reaction to see if it is complete. The aliquot taken from the reaction is spotted in its own lane ("Rxn", right), and authentic samples of A, B and C are spotted next to it on the left.
Which statement reasonably interprets the TLC results? In all cases, the reaction is defined as "complete" if no additional product C can be expected to be made by allowing the reaction to stir for a longer time.
A. The reaction is complete, and C is formed as a pure product. CH3 H H3CO H3CO A B C Rxn developing solventExplanation / Answer
In the TLC the spot of reaction mixture (Rxn) both the starting materials A and B are seen along with the product C and an additional spot below C. So, we can conclude that the reaction is incomplete, and C is formed along with a more polar impurity (Option F).
