Chapter 3.3, Problem 25E

a)

Interpretation Introduction

Interpretation:Whether compounds with zero Rf value if developed with hexane are necessarily identical or not should be determined.

Concept introduction: TLC or thin layer chromatography is technique that is used to separate various components of mixture with help of stationary phase and mobile phase. It makes use of silica gel, cellulose or aluminum oxide. This procedure is widely used because of its simplicity, low cost efficiency, and high sensitivity.

Retention factor or Rf refers to distance that is travelled by liquid to reach top of chromatographic plate. All compounds have particular value of Rf for specific solvent. This value is used for comparison of unknown samples with known compounds.

b)

Interpretation Introduction

Interpretation:Step that can be done to get nonzero value of Rf should be determined.

Can u help me figure out the reaction mechanisms for these, idk where to even start
Hi, I need your help with the drawing, please. I have attached the question along with my lab instructions. Please use the reaction from the lab only, as we are not allowed to use outside sources. Thank you!
