Inorganic Chemistry Trivia Test Quiz

2.

Which of these compounds is inorganic?

Magnesium Chloride
Pentane
Butane
Propene

Correct Answer

A. Magnesium Chloride

Explanation

Magnesium Chloride is inorganic because it does not contain carbon-hydrogen bonds. Inorganic compounds typically do not contain carbon and are often minerals or compounds of metals. Magnesium Chloride is a compound made up of magnesium, a metal, and chloride, a non-metal. It is commonly used in various industrial and medical applications. On the other hand, Pentane, Butane, and Propene are all organic compounds as they contain carbon-hydrogen bonds and are commonly found in hydrocarbons.

3.

Which of these is not a class of inorganic compounds?

Halides
Oxides
Carbonates
Actinides

Correct Answer

A. Actinides

Explanation

Actinides are not a class of inorganic compounds. Actinides are a series of radioactive elements that belong to the actinide series in the periodic table. They are classified as a group of elements, not a class of compounds. Inorganic compounds, on the other hand, are compounds that do not contain carbon-hydrogen bonds. Halides, oxides, and carbonates are all classes of inorganic compounds that contain different elements and have distinct chemical properties.

4.

Which of these is not a common characteristic of inorganic compounds?

High melting points
Ease of crystalization
High boiling points
Poor conductors

Correct Answer

A. High boiling points

Explanation

Inorganic compounds generally have high melting points, ease of crystallization, and are poor conductors of electricity. However, high boiling points are not a common characteristic of inorganic compounds. This is because inorganic compounds tend to have stronger intermolecular forces, such as ionic or covalent bonds, which require more energy to break and therefore have higher melting points. Boiling points, on the other hand, depend on the strength of intermolecular forces and the molecular weight of the compound. Inorganic compounds can have a wide range of boiling points, some of which may be high, but it is not a common characteristic.

5.

What is the simplest inorganic reaction?

Double displacement
Direct combination
Double decomposition
Reduction

Correct Answer

A. Double displacement

Explanation

Double displacement is the simplest inorganic reaction because it involves the exchange of ions between two compounds, resulting in the formation of two new compounds. This reaction is typically represented by the general equation AB + CD → AD + CB, where A, B, C, and D represent different elements or compounds. It is considered simple because it does not involve any complex rearrangement of atoms or molecules, making it easier to understand and analyze.

6.

Which of these compounds is a catalyst?

Vanadium(V) Oxide
Magnesium Chloride
Ammonium Chloride
Potassium Chloride

Correct Answer

A. Vanadium(V) Oxide

Explanation

Vanadium(V) Oxide is a catalyst because it is capable of speeding up a chemical reaction without being consumed in the process. Catalysts work by providing an alternative pathway for the reaction to occur, lowering the activation energy required for the reaction to proceed. In this case, Vanadium(V) Oxide can facilitate various reactions, such as oxidation and reduction reactions, without undergoing any permanent changes itself.

7.

Which of these is not a subdivision of inorganic chemistry?

Oganometallic chemistry
Cluster chemistry
Physical chemistry
Bioinorganic chemistry

Correct Answer

A. Physical chemistry

Explanation

Physical chemistry is not a subdivision of inorganic chemistry. Physical chemistry is a branch of chemistry that deals with the study of the physical and chemical properties of matter, as well as the changes it undergoes during chemical reactions. In contrast, organometallic chemistry, cluster chemistry, and bioinorganic chemistry all focus on the study of the properties and reactions of inorganic compounds and elements.

8.

Which of these is not an example of bioinorganic compound?

Hemoglobin
Zeolites
Methylmercury
Carboxypeptidase

Correct Answer

A. Zeolites

Explanation

Zeolites are not an example of a bioinorganic compound because they are not found in living organisms or involved in biological processes. Zeolites are a type of mineral that are commonly used as catalysts or absorbents in various industrial applications. On the other hand, hemoglobin, methylmercury, and carboxypeptidase are all examples of bioinorganic compounds. Hemoglobin is a protein found in red blood cells that carries oxygen, methylmercury is a toxic compound found in certain seafood, and carboxypeptidase is an enzyme involved in protein digestion.

9.

Which of these is not a transition metal compound?

Cisplatin
Alkoxide
Titanium tetrachloride
Iron pentacarbonyl

Correct Answer

A. Alkoxide

Explanation

Alkoxide is not a transition metal compound because it is formed by the reaction of an alcohol with a base, typically an alkali metal hydroxide. Transition metal compounds contain transition metals, which are elements in the d-block of the periodic table. Cisplatin, titanium tetrachloride, and iron pentacarbonyl are all examples of transition metal compounds.

10.

What is ammonium nitrate used for?

Catalysis
Vaccination
Soil fertilization
Reduction

Correct Answer

A. Soil fertilization

Explanation

Ammonium nitrate is commonly used as a fertilizer in agriculture due to its high nitrogen content. Nitrogen is an essential nutrient for plant growth and is necessary for the synthesis of proteins, enzymes, and chlorophyll. Ammonium nitrate provides plants with readily available nitrogen, promoting healthy growth and increased crop yields. It is often used in both commercial farming and home gardening to improve soil fertility and enhance plant nutrition.
