**Chromatography Experiment: Food Colors A and B**

**Question:**
Two food colors, A and B, have similar structures and polarities. A chromatogram for these compounds is illustrated below. 

![Chromatogram]

The diagram shows a rectangular chromatogram with the origin on the left and the solvent front on the right. There are two spots labeled:

- Spot A is closer to the origin.
- Spot B is further from the origin.

**Analysis:**
- Determine which food color, A or B, you predict to have the larger molecular weight.

**Explanation:**
In chromatography, substances that travel further typically have smaller molecular weights if the structure and polarity are similar. Based on the chromatogram, Spot A moved a shorter distance compared to Spot B. Therefore, it can be predicted that Food Color A has the larger molecular weight.
