Inorganic Chemistry Trivia Test Quiz - Quiz

Inorganic chemistry is a key part of chemistry that is concerned with the synthesis and properties of all chemical substances other than carbon-based compounds. Inorganic chemistry is closely related to organic chemistry and organometallic chemistry. Ionic compounds are inorganic. How much do you know about it? Find out in this quiz.

Questions and Answers

1.

Which of these does not apply the principles of inorganic chemistry?
- A.
  
  Materials science
- B.
  
  Catalysis
- C.
  
  Agriculture
- D.
  
  Cell culture
Correct Answer
D. Cell culture

Explanation
Cell culture does not apply the principles of inorganic chemistry. Cell culture involves the growth and maintenance of cells in a controlled environment, typically in a laboratory. It primarily focuses on the study of cell behavior, growth, and development, and does not directly involve the study of inorganic compounds or their properties. In contrast, materials science, catalysis, and agriculture all involve the application of principles of inorganic chemistry in various ways.

Which of these compounds is inorganic?
- A.
  
  Magnesium Chloride
- B.
  
  Pentane
- C.
  
  Butane
- D.
  
  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?
- A.
  
  Halides
- B.
  
  Oxides
- C.
  
  Carbonates
- D.
  
  Actinides
Correct Answer
D. 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?
- A.
  
  High melting points
- B.
  
  Ease of crystalization
- C.
  
  High boiling points
- D.
  
  Poor conductors
Correct Answer
C. 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.

What is the simplest inorganic reaction?
- A.
  
  Double displacement
- B.
  
  Direct combination
- C.
  
  Double decomposition
- D.
  
  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.

Which of these compounds is a catalyst?
- A.
  
  Vanadium(V) Oxide
- B.
  
  Magnesium Chloride
- C.
  
  Ammonium Chloride
- D.
  
  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.

Which of these is not a subdivision of inorganic chemistry?
- A.
  
  Oganometallic chemistry
- B.
  
  Cluster chemistry
- C.
  
  Physical chemistry
- D.
  
  Bioinorganic chemistry
Correct Answer
C. 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.

Which of these is not an example of bioinorganic compound?
- A.
  
  Hemoglobin
- B.
  
  Zeolites
- C.
  
  Methylmercury
- D.
  
  Carboxypeptidase
Correct Answer
B. 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.

Which of these is not a transition metal compound?
- A.
  
  Cisplatin
- B.
  
  Alkoxide
- C.
  
  Titanium tetrachloride
- D.
  
  Iron pentacarbonyl
Correct Answer
B. 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.

What is ammonium nitrate used for?
- A.
  
  Catalysis
- B.
  
  Vaccination
- C.
  
  Soil fertilization
- D.
  
  Reduction
Correct Answer
C. 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.
