Covalent Bond Questions: Quiz!

Explanation
A covalent bond is a type of chemical bond that forms between two nonmetal atoms. In this type of bond, electrons are shared equally between the atoms involved. This means that both atoms have an equal share of the electrons, creating a balanced distribution of charge. This sharing of electrons allows the atoms to achieve a stable electron configuration, making the bond strong and stable.

Explanation
The given compounds CH4, H2O, NH3 are all examples of compounds with common names. However, CO2 is not a compound with a common name. It is commonly referred to as carbon dioxide, which is its systematic name.

Explanation
Hydrogen peroxide is the common name for H2O2. It is a chemical compound consisting of two hydrogen atoms and two oxygen atoms. It is commonly used as a disinfectant and bleaching agent due to its strong oxidizing properties. Hydrogen peroxide is also used in various industries, such as pharmaceuticals, textiles, and electronics. It is important to note that while water (H2O) is also a common name for H2O2, the specific compound being referred to in this question is hydrogen peroxide.

Explanation
The correct answer is Dichlorine. The name "Dichlorine" accurately represents the compound Cl2, which consists of two chlorine atoms bonded together. The prefix "di-" indicates the presence of two chlorine atoms, while "chlorine" indicates the element itself.

Explanation
The correct answer is Germanium disulfide because it follows the naming convention for binary compounds, where the first element is named with its elemental name and the second element is named with the suffix "-ide" to indicate that it is an anion. In this case, "Germanium" is the name of the first element and "disulfide" indicates that it is a compound of two sulfur atoms.

Explanation
The name "Disulfur dibromide" accurately represents the compound S2Br2. The prefix "di" indicates that there are two bromine atoms bonded to the sulfur atoms, and "disulfur" indicates that there are two sulfur atoms in the compound. Therefore, "Disulfur dibromide" is the appropriate name for S2Br2.

Explanation
The correct answer is F2 because "difluorine" refers to a molecule consisting of two fluorine atoms bonded together. The chemical symbol for fluorine is F, so the formula for difluorine is F2.

Explanation
The correct formula for boron trichloride is BCl3. This is because boron typically forms three bonds, and chlorine is a halogen that forms one bond. Therefore, when boron combines with three chlorine atoms, it forms boron trichloride.

Explanation
Tetraphosphorus decoxide is represented by the chemical formula P4O10. The prefix "tetra-" indicates that there are four phosphorus atoms in the compound, and "decoxide" indicates that there are ten oxygen atoms. Therefore, the correct formula is P4O10.
