1.	During a column chromatography through Al_(2)O_(3) column, a mixture of components A,B and C is passed through the column. On adding eluant, compound 'A' is eluted first then 'B' and in the end 'C'. Which of the following statements regarding the components is correct ?
Answer» The ORDER of adsorption of A, B and C is `C gt B gtA` The order of adsorption of A,B and C is `A gt B gt C` The order of adsorption of A,B and C is `B gt A gt C` The order of adsorption of A, B and C is `B gt C gt A` Solution :Since compound 'A' COMES out before 'B','B' is more readily adsorbed to the column and 'B' comes out before 'C'. HENCE 'C' is more readily adsorbed than 'B'. Hence , the order of adsorption is `C gt B gt A.`
