Step 1
Which group of allotropes contain this fullerene?
Answer
The fullerene depicted in Fig. 15.1 is classified as an Inorganic allotrope of carbon. Fullerenes are molecular structures formed from carbon, and they do not fall under the organic category since they do not primarily contain carbon-hydrogen bonds typical in organic compounds.
Step 2
What is the approximate size of a molecule of this fullerene?
Answer
The approximate size of a molecule of this fullerene is about 1 × 10^{-10} m. The other options, such as 1 × 10^{-15} m, are too small for molecular dimensions, whereas 1 × 10^{-5} m indicates a much larger size than typical molecular scales.
