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

Question

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 (A) anthracene → chlorobenzene → p-cresol (B) anthracene → p-cresol → chlorobenzene (C) chlorobenzene → p-cresol → anthracene (D) chlorobenzene → anthracene → p-cresol

Tardigrade Admin · Accepted Answer

Alumina columm 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:

Anthracene

\to

chlorobenzene

\to p

-cresol

Q. 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

anthracene $\to$ chlorobenzene $\to$ p-cresol

anthracene $\to$ p-cresol $\to$ chlorobenzene

chlorobenzene $\to$ p-cresol $\to$ anthracene

chlorobenzene $\to$ anthracene $\to$ p-cresol

p-cresol $\to$ anthracene $\to$ chlorobenzene

Alumina columm 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:

Q. 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

anthracene → chlorobenzene → p-cresol

anthracene → p-cresol → chlorobenzene

chlorobenzene → p-cresol → anthracene

chlorobenzene → anthracene → p-cresol

p-cresol → anthracene → chlorobenzene
