Question
What is the primary structural feature of fullerenes that distinguishes them from other carbon allotropes?
Answer
Fullerenes are primarily based on hexagonal rings of carbon atoms, although they may also include pentagonal or heptagonal rings.
Explanation
This answer is strong because it directly addresses the structural characteristics of fullerenes, which is the focus of the learning objective. The question tests the student's understanding of the unique bonding arrangement in fullerenes compared to other carbon structures.
Common mistake
Confusing Fullerene Structure
Students often state that fullerenes are only made of hexagonal rings and do not mention the presence of pentagonal or heptagonal rings.
Emphasize that fullerene structures are primarily based on hexagonal rings but can also include rings with five or seven carbon atoms.
