A. Compound 'c' is more polar than 'a' and 'b'
B. Compound '$$\mathrm{a}$$' 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:
B and D only
B, C and D only
A, B and D only
A, B and C only
Explanation
As the chromatogram, degree of polarity
$$
\rightarrow \mathrm{a}>\mathrm{b}>\mathrm{c} \text {. }
$$
$\therefore$ 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 & C are incorrect statements.
$\therefore$ 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 & C are incorrect statements.
