Name each of the following binary molecular compounds: SO3, N2O5, N2O4, NO2, NO, N2O, SiO2, P2O4, P4O7, P4O10, Cl2O7
The Correct Answer and Explanation is :
Names of the Given Binary Molecular Compounds:
- SO₃ – Sulfur trioxide
- N₂O₅ – Dinitrogen pentoxide
- N₂O₄ – Dinitrogen tetroxide
- NO₂ – Nitrogen dioxide
- NO – Nitric oxide (or nitrogen monoxide)
- N₂O – Dinitrogen monoxide (commonly known as nitrous oxide or laughing gas)
- SiO₂ – Silicon dioxide
- P₂O₄ – Diphosphorus tetroxide
- P₄O₇ – Tetraphosphorus heptoxide
- P₄O₁₀ – Tetraphosphorus decaoxide
- Cl₂O₇ – Dichlorine heptoxide
Explanation:
Binary molecular compounds are composed of two nonmetal elements. Their naming follows a systematic approach based on prefixes that indicate the number of atoms of each element.
- Prefixes in Naming:
- Mono- (1)
- Di- (2)
- Tri- (3)
- Tetra- (4)
- Penta- (5)
- Hexa- (6)
- Hepta- (7)
- Octa- (8)
- Nona- (9)
- Deca- (10)
- Rules for Naming:
- The first element in the formula retains its element name.
- The second element is modified to end with “-ide.”
- The prefixes indicate the number of atoms, except for “mono-” on the first element (e.g., CO is carbon monoxide, not monocarbon monoxide).
- If “mono-” is used before oxygen, the “o” is dropped (e.g., monoxide instead of monooxide).
- Examples Explained:
- SO₃ (Sulfur trioxide): “Tri-” denotes three oxygen atoms.
- N₂O₅ (Dinitrogen pentoxide): “Di-” for two nitrogen, “penta-” for five oxygen.
- P₄O₁₀ (Tetraphosphorus decaoxide): “Tetra-” for four phosphorus, “deca-” for ten oxygen.
These rules ensure clarity and consistency in chemical nomenclature.
