A technician analyses three samples of hydrocarbons. The table shows the molecular formula of each hydrocarbon found in each sample.
| Sample | Hydrocarbons found in the sample |
|---|---|
| A | C3H8\text{C}_{3}\text{H}_{8}C3H8, C9H20\text{C}_{9}\text{H}_{20}C9H20, C15H32\text{C}_{15}\text{H}_{32}C15H32, C21H44\text{C}_{21}\text{H}_{44}C21H44 |
| B | C10H22\text{C}_{10}\text{H}_{22}C10H22 only |
| C | C12H26\text{C}_{12}\text{H}_{26}C12H26, C13H28\text{C}_{13}\text{H}_{28}C13H28, C14H30\text{C}_{14}\text{H}_{30}C14H30 |
