A safety officer compares three liquid hydrocarbons at the same temperature. Each liquid could leak through a narrow gap in a storage container.
| Hydrocarbon | Number of carbon atoms in each molecule | Boiling point in °C | Time for 5.0 cm³ to pass through the same narrow tube in s |
|---|---|---|---|
| J | 6 | 69 | 8.0 |
| K | 10 | 174 | 24.0 |
| L | 14 | 254 | 60.0 |
Explain which hydrocarbon presents the greatest fire risk. Use the data in the table and your knowledge of the properties of hydrocarbons.
