Question:
1. The process of applying a mixture of compounds to the top ofa column of a stationary phase is referred to as
packing
running
loading
spotting
2. Relative to the solvent, alumina and silica gel are usuallyconsidered:
extremely non-polar
extremely polar
somewhat polar
somewhat non-polar
3.If you decide to decrease the polarity of the eluent in yourchromatographic run, you should expect the speed at which acompound moves through the column to:
remain unchanged
decrease
become unpredictable
increase
4.The most powerful intermolecular interactions responsible forthe adsorption of molecules to a stationary phase like aluminaare:
large dipole-dipole interactions
hydrogen bonding interactions
small dipole-dipole interactions
london forces
please answer it as soon as possible, Thanks!
