The mixture of compounds A and B is passed through a column of `Al_(2)O_(3)` by using alcohol as eluent. Compound A is eluted in preference to compound B. Which of the compounds A or B is more readily adsorbed on the column?

Explanation

Compounds which are adsorbed to the more extent comes out later while the another one which absorbed to the lass extent comes out readily. Since, compound 'A' comes out before compound 'B', the compound 'B' is more readily adsorbed on the column.
