The largest Rf value is 1, which occurs when the compound remains at the origin of the chromatogram and does not move at all. The smallest Rf value is 0, which happens when the compound moves with the solvent front and does not adhere to the stationary phase.
To answer this question both values have to be converted to the same unit and compared afterwards. Let's convert both to inches: 1 yard = 36 inches After comparing we can see that value of 36 inches is more than value of 2 inches that makes value of 1 yard more than value of 2 inches.
It is exactly 251: 1 more than 250 and one fewer than 252.
Only a single digit can have a place value, a number with more than 1 digits cannot .
The maximum RF value that can be obtained is 1.0. This means that the substance travels the full distance of the chromatography medium being used. Any RF value greater than 1 is not physically possible.
Rf values are distance of substance from origin divided by distance of solvent front from origin. As the substance travels with the solvent, the solvent will always have a greater or equal value to the distance travelled by substance. This means the highest value of Rf is 1.

No, it's not possible to have an RF value greater than one. Rf values are a ratio of the distance a spot has traveled to the total distance of the solvent front. Since the distance of the front is always greater than the distance of a spot, the Rf value is always less than 1.
The Rf value of the xanthophyll is two thirds that of carotene because xanthophyll has an H bond with cellulose, which slows it down, and makes it less soluble in the solvent. Carotene is more soluble in 9:1 petroleum-ether acetone solution, which caused it to be carried higher and have a larger Rf value.
When the Rf value is zero, it generally refers to the position of the substance in the chromatogram. This means it did not move of that origin point.
A compound with a high Rf value (close to 1) is strongly held on the paper and moves a short distance on the chromatography plate. This means it interacts more with the stationary phase (paper) than the mobile phase (solvent) and has low solubility in the solvent.

The Rf value of decane will depend on the specific conditions of the chromatography experiment (type of solvent, type of stationary phase, etc). In general, decane is non-polar and tends to have a higher Rf value in non-polar solvents compared to polar solvents. Typically, the Rf value of decane in non-polar solvents is close to 1.
since gain is simply -Rf/Ri and is 1+Rf/Ri in case of non inverting
An Rf value of 1 means that the compound traveled the same distance as the solvent in a chromatography experiment, indicating that the compound is very soluble in the solvent and did not adhere to the stationary phase.
The largest Rf value is 1, which occurs when the compound remains at the origin of the chromatogram and does not move at all. The smallest Rf value is 0, which happens when the compound moves with the solvent front and does not adhere to the stationary phase.
