Methods of Purification of Organic Compounds

Three organic compounds $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ were allowed to run in thin layer chromatography using hexane and gave the following result (see figure). The ${\mathrm{R}}_{\mathrm{f}}$ value of the most polar compound is _____ $\times {10}^{–2}$

Which of the following statement is correct for paper chromatography?

Thin layer chromatography of a mixture shows the following observation:

The correct order of elution in the silica gel column chromatography is

Using column chromatography, mixture of two compounds ‘$\mathrm{A}$’ and ‘$\mathrm{B}$’ was separated. ‘$\mathrm{A}$’ eluted first, this indicates ‘$\mathrm{B}$’ has

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

$\mathrm{A}$. Compound ‘$\mathrm{c}$’ is more polar than ‘$\mathrm{a}$’ and ‘$\mathrm{b}$’

$\mathrm{B}$. Compound ‘$\mathrm{a}$’ is least polar

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

$\mathrm{D}$. Compound ‘$\mathrm{a}$’ spends more time in the column
