Question

From the figure of column chromatography given below, identify incorrect statements.

$A$ . Compound ‘ $c$ ’ is more polar than ‘ $a$ ’ and ‘ $b$ ’

$B$ . Compound ‘ $a$ ’ is least polar

$C$ . Compound ‘ $b$ ’ comes out of the column before ‘ $c$ ’ and after ‘ $a$ ’

$D$ . Compound ‘ $a$ ’ spends more time in the column

Choose the correct answer from the options given below

Column chromatography separates compounds based on their polarity. The more polar a compound is, the more it interacts with the stationary phase and the slower it moves through the column. The less polar a compound is, the faster it moves through the column.
As the chromatogram, degree of polarity
$\to a > b > c$
$∴$ Statements $A, B$ are incorrect as $b$ comes out before ‘ $C$ ’ the statement $C$ is also incorrect.
As $a$ is most polar, it spends most time. Hence, $A, B$ and $C$ are incorrect statements.
