Questions & Step-by-Step Solutions
Which of the following compounds would you expect to show strong absorption in the UV region?
Step 1: Understand what UV absorption means. UV absorption occurs when a compound can absorb ultraviolet light.
Step 2: Identify the types of compounds. Aromatic compounds have a special structure with delocalized π electrons, while alkanes are simple hydrocarbons without this structure.
Step 3: Recognize that delocalized π electrons in aromatic compounds can interact with UV light, allowing them to absorb it.
Step 4: Compare aromatic compounds to alkanes. Alkanes do not have delocalized π electrons, so they do not absorb UV light.
Step 5: Conclude that aromatic compounds will show strong absorption in the UV region, while alkanes will not.
