Homework Help: Chemistry!!!

1.)The silica that makes up the stationary phase in TLC chromatophraphy is more polar than the mobile phase. What then might the relative positions of the analgesics on the developed TLC plate tell you about the polarity of these molecules? Does this match the expectations based on their structures?

2.) How can TLC be used to test the purity of a substance?
