Question

Match the pigments given in List I with their colour in chromatogram given in List II.

List-I (Pigments)		List-II (Colour in chromatogram)
1	Chlorophyll 'b'	p	Yellow orange
2	Carotenoids	q	Orange red
3	Chlorophyll 'a'	r	Yellow
4	Xanthophylls	s	Blue green
		t	Yellow green

Choose the correct option from the following :

• A. 1-s, 2-t, 3-r, 4-q
• B. 1-p, 2-q, 3-r, 4-t
• C. 1-t, 2-p, 3-s, 4-r
• D. 1-t, 2-p, 3-r, 4-s

Hint:

Chromatography helps separate plant pigments based on their solubility and interaction with the solvent.

Answer 1

The Correct Option is B

Plant pigments separate into distinct bands during chromatography due to their solubility and polarity.
- Chlorophyll ‘b’ appears yellow-green.
- Carotenoids show yellow-orange.
- Chlorophyll ‘a’ appears blue-green.
- Xanthophylls show yellow.
