The elution sequence of a mixture of compounds containing chlorobenzene, anthracene and p-cresol developed of an alumina column using a solvent system of progressively increasing polarity is

Options

A. anthracene chlorobenzene p-cresol
B. anthracene p-cresol chlorobenzene
C. chlorobenzene p-cresol anthracene
D. chlorobenzene anthracene p-cresol

Answer

A

Explanation

Alumina column having suitable solvent elutes the species based on their nature of polarity. Less polar species adsorb first and more polar there after. Thus the correct order is: Anthrancene `rarr` chlorobenzene `rarr` p-cresol
