A mixture containing 1-phenylethanol, benzoic acid and tert-butylbenzene were separated by column chromatography. Using neutral alumina as the stationary phase and ether as the eluent, the order in which these compounds leave the column is:
a.
tert-butylbenzene, 1-phenylethanol, benzoic acid
b.
benzoic acid, 1-phenylethanol, tert-butylbenzene
c.
1-phenylethanol, benzoic acid, tert-butylbenzene
