Nitrogen oxides include several compounds formed from nitrogen and oxygen, such as nitric oxide, nitrogen dioxide, nitrous oxide, and nitrogen pentoxide.
Oxides of nitrogen, commonly known as NOx, are a group of gases composed of nitrogen and oxygen. These compounds vary in their chemical formulas and properties.
Based on the provided reference, the different types of nitrogen oxides include:
- Nitric Oxide (NO): This is one of the two nitrogen oxide compounds highlighted as toxicologically significant.
- Nitrogen Dioxide (NO₂): Alongside nitric oxide, nitrogen dioxide is noted as being toxicologically significant.
- Nitrogen Monoxide (or Nitrous Oxide, N₂O): This gas also belongs to the group of nitrogen oxides.
- Nitrogen Pentoxide (NO₅): Nitrogen pentoxide is another gas included in this group.
Here's a summary of the types mentioned:
| Type | Chemical Formula | Significance (from Reference) |
|---|---|---|
| Nitric Oxide | NO | Toxicologically significant |
| Nitrogen Dioxide | NO₂ | Toxicologically significant |
| Nitrogen Monoxide | N₂O | Belongs to this group |
| Nitrogen Pentoxide | NO₅ | Belongs to this group |
While the term "oxides of nitrogen" encompasses various combinations of nitrogen and oxygen, nitric oxide (NO) and nitrogen dioxide (NO₂) are particularly emphasized for their toxicological relevance. The reference confirms that nitrous oxide (N₂O) and nitrogen pentoxide (NO₅) are also part of this chemical family.
