What is the order that these four compounds would travel through a silica gel column during liquid chromatography?
a) ethylene glycol, HOCH2CH2OH
b) aqueous sodium chloride solution, NaCl (aq)
c) propanol, CH3CH2CH2OH
d) benzene, C6H6
(eluted first), ???, ???, ???, ??? (eluted last)

I was thinking: d, c, a, b
