- Avoid inhalation of vapors by working in a well-ventilated area or using a fume hood.
- Store the compound in a cool, dry place away from heat sources and incompatible substances.
- In case of skin contact, wash thoroughly with soap and water.
- In case of ingestion, seek medical attention immediately.
🛑 Note: Always refer to the Material Safety Data Sheet (MSDS) for specific handling and safety instructions.
Comparative Analysis with Other Alkanes
To better understand 2,2,3-Dimethylpentane, it's helpful to compare it with other alkanes, particularly its linear counterpart, heptane. The following table highlights some key differences:
| Property | 2,2,3-Dimethylpentane | Heptane |
|---|---|---|
| Molecular Formula | C7H16 | C7H16 |
| Boiling Point | Approximately 93°C | Approximately 98°C |
| Melting Point | Approximately -115°C | Approximately -91°C |
| Density | Approximately 0.68 g/mL | Approximately 0.684 g/mL |
| Structure | Branched | Linear |
As seen in the table, the branched structure of 2,2,3-Dimethylpentane results in a lower boiling point and melting point compared to heptane. This difference is due to the reduced intermolecular forces in the branched alkane, which affects its physical properties.
