QUESTIONS
1. What will be the result of the following errors in TLC technique? (a) Too much sample applied (b) Solvent with too high polarity (c) Solvent pond too deep in the developing chamber.
2. The polarity of a solvent (and hence it's eluting power) may be related to the dielectric constant of the solvent. Find the dielectric constants of the following solvents and arrange them in order of increasing solvent power.
Acetone, benzene, chloroform, clichlommethanc, diethyl ether, ethanol, ethyl acetate, methanol, toluene.
Two compounds spotted on a TLC plate (silica gel, ethyl acetate solvent) follow the solvent front.
Does this show that they are identical? What additional chromatography would be appropriate?
