Question
**Understanding Retention Factor (Rf) in Chromatography**

In chromatography, the retention factor (Rf) is used to characterize the movement of a compound on a chromatographic plate. It provides insight into how far a compound has traveled relative to the solvent front. The equation for determining Rf is crucial in analyzing chromatographic results.

**Question:**
What is the equation for retention factor (Rf)?

**Options:**

1. (distance traveled from the origin to the compound) / (distance traveled by the origin to the solvent front)
2. (distance traveled from the bottom of the plate to the compound) / (distance traveled from the bottom of the plate to the solvent front)
3. (distance traveled from the bottom of the plate to the solvent front) / (distance traveled from the bottom of the plate to the compound)
4. (distance traveled from the origin to the solvent front) / (distance traveled from the origin to the compound)

The correct equation for calculating the retention factor (Rf) is:

**Option 1**: (distance traveled from the origin to the compound) / (distance traveled by the origin to the solvent front)

This definition allows for a standardized ratio that makes it possible to compare the behavior of different compounds under similar conditions in chromatographic analysis.
