In this reaction, how do you determine the reaction is complete? OH OH + H,C CH, H,C он OH acetic anhydride O. acetic acid salicylic acid CILO) CH, acetylsalicylik acid Compare the reaction mixture vs. reactant on a polar TLC plate. The A disappearance of a spot with a higher Rf indicates the completion of the reaction. Compare the reaction mixture vs. reactant on a polar TLC plate. The appearance of a spot with a lower Rf indicates the completion of the reaction. Compare the reaction mixture vs. the reactant on a polar TLC plate. Once the spot with a lower Rf value disappears, the reaction should come to an end. There are no difference in Rf value for the D compounds in this reaction.
