Which of the following is the correct name for N2O5
Dinitrogen Pentoxide Nitrogen dioxide Dinitrogen Pentaoxygen
The Correct Answer and Explanation is :
The correct name for N₂O₅ is Dinitrogen Pentoxide.
Explanation:
- Understanding Chemical Nomenclature:
- N₂O₅ is a molecular (covalent) compound composed of two nitrogen (N) atoms and five oxygen (O) atoms.
- Covalent compounds are named using prefixes to indicate the number of atoms present.
- Breaking Down the Name:
- “Dinitrogen”: The prefix “di-” means two, indicating two nitrogen atoms.
- “Pentoxide”: The prefix “penta-” means five, indicating five oxygen atoms. The “a” in “penta-” is dropped before “oxide” for ease of pronunciation.
- Why Not the Other Options?
- Nitrogen dioxide (NO₂): This refers to a different compound consisting of one nitrogen atom and two oxygen atoms.
- Dinitrogen Pentaoxygen: This is incorrect because “oxide” (not “oxygen”) is used in naming compounds with oxygen.
- Properties of Dinitrogen Pentoxide:
- It is a colorless, crystalline solid at low temperatures but decomposes into NO₂ and O₂ at room temperature.
- It is highly reactive and used as an oxidizing agent.
- It plays a role in the production of nitric acid.
Thus, the systematic and IUPAC-correct name for N₂O₅ is Dinitrogen Pentoxide.
Now, I’ll generate an image representing N₂O₅ visually.
