1. What is the retention factor for the following TLC plate if the baseline is 1 cm, elute solvent traveled 5cm, and the spot of interest traveled 2.5cm?
a) 0.50
b) 1.6
c) 0.63
d) 1.4
10. Column chromatography employs both a stationary and a mobile phase. Which of the compounds listed below is commonly used as the stationary phase in column chromatography?
a) decolonizing charcoal
b) sodium bicarbonate
c) benzoic acid
d) silica gel
Homework Answers
Retention factor - distance of spot / distance of solvent
Retention factor - 2.5/5 = 0.50
Stationary phase in Tlc is we genrallyy use silica gel.

Thin Layer Chromatography (TLC) is a common technique that is routinely used in chemistry labs. It is simple, inexpensive, and very useful. Select the TRUE statement. More polar compounds travel faster on a TLC plate than less polar compounds. If compound A has a smaller Rf value than compound B, we can conclude that compound A is more polar than B. The stationary phase of a TLC silica gel plate is nonpolar. Rr is calculated as the distance traveled...

8.5 TLC is commonly employed with column chromatography to monitor the separation of colorless compounds. The column is allowed to elute into many containers, usually test tubes. This is followed by a TLC on a long plate containing the same stationary phase as the column chromatography. Since a large number of tubes must be spotted, by spotting only every other (or every three etc.) tube on the plate. After visualization (by UV), the TLC plate is used to judge which...

A silica gel TLC plate was spotted using compounds A-D and developed in hexane. Spot “B” traveled a distance of 2.0 cm from the solvent front at 4.0 cm, which of the following is a correct way to calculate its Rf value? Spot Distance traveled (cm) A 0.50 B 2.0 C 3.0 D 1.0 Spot B Rfis 4.0 cm/0.20 cm = 2.0 Spot B Rf is 4.0 cm/(4*2.0 cm) = 0.50 Spot B Rfis 2.0 cm/4.0 cm = 0.50 Spot...
