Question: Which of the following compounds would you expect to absorb UV light?

Options:

Correct Answer: Aromatic compounds

Solution:

Aromatic compounds have delocalized π electrons that can absorb UV light, while alkanes and alcohols do not have such electronic transitions.

Which of the following compounds would you expect to absorb UV light?

Which of the following compounds would you expect to absorb UV light?

Step 1: Understand what UV light absorption means. It refers to the ability of a compound to absorb ultraviolet light due to its electronic structure.
Step 2: Identify the types of compounds mentioned: aromatic compounds, alkanes, and alcohols.
Step 3: Learn about aromatic compounds. They have a special structure with delocalized π electrons, which means their electrons can move freely and can absorb UV light.
Step 4: Understand alkanes and alcohols. These compounds do not have delocalized π electrons, so they cannot absorb UV light effectively.
Step 5: Conclude that only aromatic compounds are expected to absorb UV light, while alkanes and alcohols do not.
