Step 1: Understand the Setup

In column chromatography:
- A polar adsorbent (silica gel or alumina) is the stationary phase
- A liquid solvent is the mobile phase
- Compound A eluted first → it spends less time on the column
- Compound B eluted second → it is retained longer on the column

Step 2: Relate Elution Order to Adsorption Strength

Compound that elutes first (A):
- Has weaker adsorption on the stationary phase
- Has higher  value (moves more with the solvent)

Compound that elutes seco
