Q
Q: Which of the following compounds would you expect to absorb UV light?
Solution: Aromatic compounds have delocalized π electrons that can absorb UV light, while alkanes and alcohols do not have such electronic transitions.
Steps: 5
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.
