  • 2. 

    The name for a molecular coumpound with a 3 after it is called ______________

    • Di

    • Penta

    • Tri

    Correct Answer
    A. Tri
    Explanation
    When a molecular compound has a numerical prefix after it, it indicates the number of atoms of each element in the compound. In this case, the numerical prefix is "3", which means there are three atoms of each element in the compound. The correct name for a molecular compound with three atoms of each element is "Tri".

    NI3 in a molecular compound would be called ________________

    • Sulfur Hexafluoride

    • Carbon tetrachloride

    • Nitrogen triiodide

    Correct Answer
    A. Nitrogen triiodide
    Explanation
    NI3 in a molecular compound would be called Nitrogen triiodide because it is composed of one nitrogen atom and three iodine atoms. The prefix "tri-" indicates the presence of three iodine atoms, and "nitrogen" is the name of the central atom. Therefore, the compound is named Nitrogen triiodide.

  • 4. 

    CCI4 in a molecular compound would be called ________________

    • Sulfur Hexafluoride

    • Carbon tetrachloride

    • Iodine Heptafluoride

    Correct Answer
    A. Carbon tetrachloride
    Explanation
    Carbon tetrachloride is a molecular compound that consists of one carbon atom and four chlorine atoms. According to the naming rules for molecular compounds, the prefix "tetra-" is used to indicate the presence of four chlorine atoms. Therefore, CCI4 in a molecular compound would be called carbon tetrachloride.

    Rate this question:

  • 5. 

    PCI5 in a molecular compound would be called ________________

    • Phosphorus pentachloride

    • Sulfur Hexafluoride

    • Carbon Monoxide

    Correct Answer
    A. Phosphorus pentachloride
    Explanation
    The correct answer is Phosphorus pentachloride because it follows the naming convention for molecular compounds, where the first element is named first followed by the second element with an -ide ending. In this case, "phosphorus" is the first element and "chloride" is the second element, and the prefix "penta-" indicates that there are five chlorine atoms bonded to one phosphorus atom.

    Rate this question:

  • 6. 

    IF7  in a molecular compound would be called ________________

    • Nitrogen triiodide

    • Iodine Heptafluoride

    • Phosphorus pentachloride

    Correct Answer
    A. Iodine Heptafluoride
    Explanation
    The correct answer is Iodine Heptafluoride because IF7 is the chemical formula for Iodine Heptafluoride.

    Rate this question:

  • 7. 

    The name for a molecular coumpound with a 2 after it is called ______________

    • Di

    • Mono

    • Tri

    Correct Answer
    A. Di
    Explanation
    When a molecular compound has a 2 after it, it indicates that there are two atoms of that compound present. In this case, the correct answer is "Di" because it represents the prefix for two. So, a molecular compound with a 2 after it is called "Di" to indicate that there are two atoms of that compound.

    Rate this question:

  • 8. 

    SiO2 in a molecular compound would be called ________________

    • Sulfur Hexafluoride

    • Nitrogen triiodide

    • Silicon Dioxide

    Correct Answer
    A. Silicon Dioxide
    Explanation
    SiO2 is the chemical formula for silicon dioxide, which is a molecular compound. Therefore, the correct name for SiO2 in a molecular compound would be Silicon Dioxide.

    Rate this question:

  • 9. 

    SF6 in a molecular compound would be called ________________

    • Nitrogen triiodide

    • Silicon Dioxide

    • Sulfur Hexafluoride

    Correct Answer
    A. Sulfur Hexafluoride
    Explanation
    SF6 is a compound consisting of sulfur and fluorine atoms. The prefix "hexa-" indicates that there are six fluorine atoms bonded to one sulfur atom. Therefore, the name "Sulfur Hexafluoride" accurately describes the composition of this molecular compound.

    Rate this question:

  • 10. 

    The name for a molecular coumpound with a 1 after it is called ______________

    • Tri

    • Mono

    • Di

    Correct Answer
    A. Mono
    Explanation
    When a molecular compound has a "1" after it, it indicates that there is only one atom of each element present in the compound. The prefix "mono" is used to represent the number one in chemical nomenclature. Therefore, the correct name for a molecular compound with a "1" after it is "mono".

    Rate this question:

  • 11. 

    The name for a molecular coumpound with a 4 after it is called ______________

    • Hexa

    • Tri

    • Tetra

    Correct Answer
    A. Tetra
    Explanation
    When a molecular compound has a number after it, it indicates the number of atoms of each element in the compound. In this case, the number is 4, so the compound is called "Tetra." The prefix "tetra" means four, so it accurately describes the composition of the compound.

    Rate this question:

  • 12. 

    The name for a molecular coumpound with a 6 after it is called ______________

    • Tetra

    • Hexa

    • Penta

    Correct Answer
    A. Hexa
    Explanation
    The name for a molecular compound with a 6 after it is called "Hexa". The prefix "Hexa" indicates that there are six atoms of the element present in the compound. In chemistry, prefixes are used to indicate the number of atoms of each element in a compound. In this case, "Hexa" specifically refers to six atoms.

    Rate this question:

  • 13. 

    The name for a molecular coumpound with a 7 after it is called ______________

    • Tri

    • Hepta

    • Penta

    Correct Answer
    A. Hepta
    Explanation
    The prefix "hepta" indicates the presence of 7 atoms of a particular element in a compound. Therefore, a molecular compound with a 7 after it would be called "hepta." This prefix is commonly used in chemistry to denote the number of atoms present in a compound, making it easier to identify and name different compounds.

    Rate this question:

  • 14. 

    The name for a molecular coumpound with a 5 after it is called ______________

    • Penta

    • Di

    • Hepta

    Correct Answer
    A. Penta
    Explanation
    The correct answer is "Penta." In chemical nomenclature, the prefix "penta-" is used to indicate the presence of five atoms or groups of atoms in a molecule. Therefore, when a molecular compound has a "5" after it, it is called "penta." This prefix is commonly used in naming compounds such as pentane, pentanol, or pentene, which all contain five carbon atoms.
