Paper chromatography

(show complete solution)

Paper Chromatography monitored using paper chromatography. Compounds A and B were mixed and a sample of the solution was spotted every thirty minutes. The same stationary phase and mobile phase were used throughout the experiment. The figure below shows chromatograms of standards A and B, and the sample at different time points. Hint: C is less polar than D. The progress of a hypothetical reaction: A + B → C + D, was
