Which component has Rf value of 1?
Blue.
Why can't an RF value of more than 1 be calculated?
An RF (retention factor) value greater than 1 cannot be calculated because it represents the ratio of the distance traveled by a compound to the distance traveled by the solvent front on a chromatography plate. If a compound travels further than the solvent front, it suggests that the compound has not interacted properly with the stationary phase, which is not a valid scenario in chromatography. Therefore, RF values are always between 0 and 1, indicating that the compound can only travel a distance equal to or less than the solvent front.
What are largest and smallest Rf values?
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.
Which is more 1 yard or 2 inches?
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.
What is the value of 251?
It is exactly 251: 1 more than 250 and one fewer than 252.
What is the maximum and RF value can be?
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.
Why are Rf values always less than 1?
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.

Is it possible to have a Rf value greater than 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.
Why does carotene have the highest Rf value?
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.
If a particular compound has a Rf value of 0.95 is it strongly held on the paper or in the solution?
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.
What does it mean when the Rf value is less then 0?
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.
How do you convert the following RF scale to direct statement 1 500 000?
1:50000 cm 1 cm=50000 divide by one humdred thousand.km 1 cm=0.5 km.
What is the Rf value of decane?
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.
Why you used inverting op amp more than non inverting op amp?
since gain is simply -Rf/Ri and is 1+Rf/Ri in case of non inverting
What are largest and smallest Rf values?
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.
