Chemistry 121 Molecular Compounds

CO in a molecular compound would be called Carbon Monoxide. This is because CO is a chemical formula that represents a compound composed of one carbon atom and one oxygen atom. The name "Carbon Monoxide" is derived from the elements present in the compound.

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.

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.

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.

The correct answer is Iodine Heptafluoride because IF7 is the chemical formula for Iodine Heptafluoride.

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.

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".

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.

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.

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".

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.

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.

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.

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.
