University of Maryland Baltimore County TLC Analysis and Purity of Sample Paper

 

I’m working on a chemistry question and need an explanation to help me learn.

A synthesis of lidocaine was done. The first P is the lidocaine precursor. Describe what you can confidently conclude, and what you cannot conclude, regarding the purity of the sample by TLC analysis. For example, have all of the starting material(s), solvent(s), purification materials, been successfully removed from the final sample?
