- Why is it more difficult to optimize k' and α in HPLC than in GC hand written please.A student performs a TLC experiment and at the end of the experiment, sees no spots other than the initial spot. What does this mean, and what should the student do to fix the problem?If the TLC plates had been developed in a more polar solvent, would retention factors on the whole be larger, smaller, or unchanged? Briefly (1 - 2 sentences) explain your reasoning
- Use this video to answer the questions: https://www.youtube.com/watch?v=BocfSXdbaU0Concentrated sulfuric acid, H2SO4, was used to visualize the sugars (cellobiose and glucose), whose identities were confirmed by TLC. Describe the mechanism by which the sulfuric acid, H2SO4, produces visible spots where sugars are present on the TLC plateA TLC plate was run in cyclohexane:ethyl acetate 4:1, the pure product, 2 starting materials and final product were spotted. what does the tlc tell you about the product.
