A computer model produces four structures made only from carbon atoms.
The table shows the ring sizes and overall shape of each structure.
| Structure | Sizes of carbon rings present | Overall shape |
|---|---|---|
| P | 5 and 6 | curved open sheet |
| Q | 5 and 6 | closed hollow cage |
| R | 6 and 7 | hollow tube |
| S | 6 and 8 | closed hollow cage |
Explain which two structures could be fullerenes.
