A radical bromination experiment is conducted. Dichloromethane (solvent) and an unknown hydrocarbon is added to each test tube. Bromine (Br2) is then added to the test tube to determine relative reaction rates.

Imagine that you carried out the experiment, but used an additional unknown compound ("Unknown #7"). Assume that the experiment was carried out perfectly (perfect technique, clean glassware, compounds were all correct and pure, no side reactions occurred in either experiment setup, etc.) and the following scenario is completely reproducible.

You noted the following observations: The solution containing Unknown #7 became completely colorless after 18 minutes of exposure to ambient light, or after 6 minutes when placed in front of the provided light. You also noticed that under ambient conditions the solution became colorless but cloudy. When the experiment was carried out in front of the light source the solution became colorless, but not cloudy. After the solution became colorless you discarded it immediately.

Given that you do not know the structure of Unknown 7, provide your best hypothesis to explain this experimental observation of cloudiness.
