1. How does chromatography separate the components of leave samples? 2. Can you use chromatography to purify a mixture? why? 3. What is Rf value and its significance in chromatography?
How else can chromatography be used? None of these answers are correct. To wash (or remove) unwanted solvents from a mixture. To identify or exclude components in a mixture. To generate IUPAC names for hydrocarbons.
Use a suitable model to explain how separation and identification of a mixture of organic compounds can be achieved with a thin layer chromatographic (TLC) technique.
Use the following information and data to answer the question. A student is performing a paper chromatography experiment. He spots two sample compounds (compound A and compound B) on the origin line at the bottom of his paper. He then places the paper into a beaker with a centimeter or so of liquid solvent and allows it to develop until the solvent front is near the top of the paper. Compound A eluted 8.23 cm up the paper. Compound B eluted 4.77 cm up the paper. The solvent front (distance solvent eluted) was measured at 10.46 cm from the origin. In terms of the properties of the two samples (A and B) it can be said: a) sample A has the highest affinity for the paper b) sample B has the highest affinity for the paper c) the affinities of the samples are the same d) sample B has the lowest affinity for the paper
