Assertion : A mixture of plant pigments can be separated by chromatography. Reason : Chromatography is used for the separation of coloured substances into individual components.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Chromatography is an important technique extensively used to separate mixtures into their components, purify compounds and also to test the purity of compounds. It is used for both coloured and colourless compounds. So, the option (2) is correct.

Thin layer chromatography of a mixture shows the following observation:
The correct order of elution in the silica gel column chromatography is
1 \(\mathrm{A}>\mathrm{C}>\mathrm{B}\)
2 \(\mathrm{B}>\mathrm{C}>\mathrm{A}\)
3 \(\mathrm{C}>\mathrm{A}>\mathrm{B}\)
4 \(\mathrm{B}>\mathrm{A}>\mathrm{C}\)
Explanation:
According to the observation, A is more stable and interacts with the mobile phase more than C , and C is more drawn to the mobile phase than B. Hence, the correct order of elution in the silica gel column chromatography is: B \( < \) C \( < \) A.
