Understand the Problem
The question is asking for answers to a series of chemistry-related sub-questions, which includes identifying functional groups, oxidation states, historical figures in chemistry, and properties of specific compounds.
Answer
1) –SO₃H 2) -½ 3) Kekule 4) BF₃ 5) Radicals
- –SO₃H 2) -½ 3) Kekule 4) BF₃ 5) Radicals
Answer for screen readers
- –SO₃H 2) -½ 3) Kekule 4) BF₃ 5) Radicals
More Information
Sulfonic acids have the group –SO₃H. The oxygen in KO₂ has an unusual oxidation number due to the superoxide ion. Friedrich August Kekulé proposed the benzene structure with delocalized electrons. BF₃ is a classic electrophile due to its electron deficiency. Homolytic cleavage results in radicals.
Tips
A common confusion when determining oxidation numbers is forgetting to account for the specific charges involved in unique ions like superoxides.
