The elution sequence of a mixture of compounds containing chlorobenzen

1.	The elution sequence of a mixture of compounds containing chlorobenzene, anthracene and p-cresol developed on an alumina column using a solvent system of progressively increasing polarity isA. anthracene `rarr`chlorobenzene `rarr` p-cresolB. anthracene `rarr` p-cresol `rarr` chlorobenzeneC. chlorobenzene `rarr` anthracene `rarr` p-cresolD. p-cresol `rarr` anthracene `rarr` chlorobenzene
Answer» Correct Answer - A Sequence of elution upon the polarity of the compound to be eluted , higher the polarity, later is the sequence of elution. Anthracene being least polar is eluted first, followed by chloro-benzene having little higher polarity while p-cresol being most polar is eluted last of all. Thus, option (a) is correct.
