What does a high RF value mean?
Understand the Problem
The question is asking about the significance of a high RF (retention factor) value, which is commonly used in chromatography to describe the mobility of compounds during the separation process.
Answer
The compound has high solubility in the mobile phase and tends to be non-polar.
A high RF value means the compound has high solubility in the mobile phase and tends to be non-polar.
Answer for screen readers
A high RF value means the compound has high solubility in the mobile phase and tends to be non-polar.
More Information
In chromatography, higher RF values generally indicate compounds that move further on the plate due to their strong interactions with the mobile phase and their non-polar nature.
Tips
A common mistake is to assume that a high RF value indicates a compound is polar. In most chromatography setups, it's the opposite; non-polar substances typically have higher RF values.
