Do alkanes react?
Alkanes (the most basic of all organic compounds) undergo very few reactions. The two reactions of more importaces is combustion and halogenation, (i.e., substitution of a single hydrogen on the alkane for a single halogen) to form a haloalkane.
Are alkanes dangerous?
Cycloalkanes are more toxic than alkanes or branched alkanes [878]. In humans, high concentrations of inhaled alkanes can result in anesthetic effects or narcosis [878]. Alkanes are CNS depressants [855]. However, high molecular weight alkanes are considered virtually non toxic [878].
Why are halogenated hydrocarbons bad?
These halogenated hydrocarbons can induce toxicity after biotransformation to multiple organs, especially kidney in experimental animals, and is a concern about the potential human health.
How do we use alkanes in daily life?
Common usage of alkanes in natural gas
- heating/cooling house (air conditioning)
- ovens.
- fireplaces.
- outdoor lights.
- Fuel cells.
- plastic products (from cracking of ethane, propane)
- fertilizer (in Haber-Bosch process for production of ammonia, hydrogen comes from methane)
- fabric.
Which materials are alkanes?
Table of alkanes
| Alkane | Formula | Density [kg/m3] (at 20 °C) |
|---|---|---|
| Methane | CH4 | 0.656 (gas) |
| Ethane | C2H6 | 1.26 (gas) |
| Propane | C3H8 | 2.01 (gas) |
| Butane | C4H10 | 2.48 (gas) |
How are alkanes used in everyday life?
Alkanes are very versatile and are being used as solvents, heating oils, fuels, in fat synthesis, in the synthesis of fatty acids by air oxidation, in the manufacture of albumen, in the transformation to olefins, etc.
