How does saturation effect RF value?

In general, as saturation increases, the RF value decreases. This is because an increase in saturation tends to increase retention of the compound on the stationary phase, resulting in a lower RF value. Conversely, lower saturation levels may allow the compound to move more freely, leading to a higher RF value.
