Mark the incorrect match w r t the colour of the pigments in the chromatogram

Options

A. Chlorophyll a - Blue green
B. Chlorophyll b - Yellow green
C. Xanthophylls - Orange green
D. Carotene - Yellow orange

Answer

To solve the question regarding the incorrect match with respect to the color of pigments in the chromatogram, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Chromatography**:
- Chromatography is a technique used to separate different pigments based on their molecular weight. The result of this separation is visualized on a paper or slide, which is referred to as a chromatogram.

2. **Analyzing Each Pigment**:
- **Chlorophyll A**: This pigment is known to exhibit a blue-green color in the chromatogram.
- **Match**: Chlorophyll A - Blue Green (Correct)

- **Chlorophyll B**: This pigment shows a yellow-green color.
- **Match**: Chlorophyll B - Yellow Green (Correct)

- **Xanthophyll**: Xanthophyll is typically seen as a pale yellow or yellowish-green color, not orange-green.
- **Match**: Xanthophyll - Orange Green (Incorrect)

- **Carotene**: Carotene is recognized for its bright yellow to yellow-orange color.
- **Match**: Carotene - Yellow Orange (Correct)

3. **Identifying the Incorrect Match**:
- From the analysis, the incorrect match is with Xanthophyll, which is not orange-green but rather pale yellow or yellowish-green.

### Conclusion:
The incorrect match with respect to the color of pigments in the chromatogram is:
- **Xanthophyll - Orange Green**.
