Naming and Writing the Formulas of Binary Covalent Compounds. Complete the missing information in the following table. Formula of Covalent Compound CS2 OF2 P4O10 N2O4 SO3 Name of Covalent Compound Carbon di Sulfide Oxygen di fluoride Tetra Phor phorus decacoxide dinutrogen Tetraoxide Sulfur Trioxide P13 CBr4 N2O2 SO2 Cl2O phosphorus triiodide carbon tetrabromide dinitrogen dioxide sulfur dioxide dichlorine monoxide
The Correct Answer and Explanation is:
Here is the correctly formatted table with the proper names of the binary covalent compounds:
| Formula of Covalent Compound | Name of Covalent Compound |
|---|---|
| CS₂ | Carbon disulfide |
| OF₂ | Oxygen difluoride |
| P₄O₁₀ | Tetraphosphorus decoxide |
| N₂O₄ | Dinitrogen tetroxide |
| SO₃ | Sulfur trioxide |
| PI₃ | Phosphorus triiodide |
| CBr₄ | Carbon tetrabromide |
| N₂O₂ | Dinitrogen dioxide |
| SO₂ | Sulfur dioxide |
| Cl₂O | Dichlorine monoxide |
Binary covalent compounds consist of two non-metal elements. The naming follows a systematic approach using prefixes to indicate the number of atoms of each element. The first element retains its standard name, while the second element adopts an -ide suffix. Greek prefixes indicate quantity except when the first element appears alone.
For example, carbon disulfide has one carbon atom and two sulfur atoms. The prefix di signifies two sulfur atoms. Oxygen difluoride follows the same principle, with one oxygen and two fluorine atoms.
Tetraphosphorus decoxide consists of four phosphorus atoms and ten oxygen atoms, with tetra indicating four and deca representing ten. Dinitrogen tetroxide follows similar logic, denoting two nitrogen atoms and four oxygen atoms.
Sulfur trioxide contains one sulfur atom and three oxygen atoms, while phosphorus triiodide includes three iodine atoms. Carbon tetrabromide has four bromine atoms, and dinitrogen dioxide shows two nitrogen atoms and two oxygen atoms.
Sulfur dioxide contains two oxygen atoms, while dichlorine monoxide has one oxygen atom. The mono prefix is used only for the second element.
Understanding these rules aids in recognizing molecular composition and predicting compound behavior. Mastery of binary covalent nomenclature strengthens foundational chemistry knowledge and supports further study in molecular structures.
