The mixture of compounds A and B is passed through a column of Al2O3 by using alcohol as eluant. Compound A is eluted in preference to compund B. Which of the compunds A or B, is more readily adsorbed on the column?

NEETprep Answer:
 
Compunds which are adsorbed to the more extent comes out later while the another one which absorbed to the less extent comes out readily. Since, compound 'A' comes out before 'B', the compound 'B' is more readily adsorbed on the column.
