a. Using the chromatogram of a 2:8, tert-butanol/ethanol mixture, write a concise discussion indicating: (1) which compound interacts more with the stationary phase utilized in this experiment, and (2) if this experimental result would be consistent with a polar or non-polar stationary phase.

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.

It is kept in an engine.hope it
