Paracetamol is a fairly polar molecule while lycopene is not. If you are using a polar mobile phase through a C-18, which compound will have a shorter retention time? lycopene They will not separate and elute at the same time Cannot be determined since the identity of the mobile phase must be known Cannot be determined since it is a C-18 column paracetamol

If the stationary phase and the compound being tested are both polar, will the retention factor (Rf) likely be smaller or larger than if a nonpolar compound was tested? Why? 1) The retention factor will likely be smaller as it has a smaller interaction with the stationary phase O 2) The retention factor will likely be greater as it has a smaller interaction with the stationary phase O3) The retention factor will likely be smaller as it has a greater interaction with the stationary phase 4) The retention factor will likely be greater as it has a greater interaction with the stationary phase

diantilis ether. find the peaks

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.

What is the equation for retention factor (Rf)? 1) (distance traveled from the origin to the compound)/(distance traveled by the origin to the solvent front) (distance traveled from the bottom of the plate to the compound)/(distance O 2) traveled from the bottom of the plate to the solvent front) 3) (distance traveled from the bottom of the plate to the solvent front)/(distance traveled from the bottom of the plate to the compound) 4) (distance traveled from the origin to the solvent front)/(distance traveled from the origin to the compound)
