Free Reactions of Group IV Elements MCQs with Answers
62 Reactions of Group IV Elements MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.

- A. H2SnO3
- B. H2SiO3
- C. H3AsO4
- D. H3SbO4
Explanation: Metasilicic acid has the formula H2SiO3, commonly represented as SiO(OH)2, whereas orthosilicic acid is H4SiO4.
Correct answer: H2SiO3- A. Ch3
- B. OH
- C. OCH3
- D. O2
Explanation: The intended comparison is between silicone and silica: silicone polymers contain repeating Si-O units with organic groups such as CH3…
Correct answer: Ch3- A. Acidic oxide
- B. Basic oxide
- C. Amphoteric oxide
- D. It does not exists
Explanation: Aluminium oxide reacts with both acids and bases, forming aluminium salts with acids and aluminates with bases, so it is amphoteric.
Correct answer: Amphoteric oxide- A. Heat resistant
- B. Low melting
- C. Used to prepare chemical garden
- D. Green in colour
Explanation: Borate and borosilicate glasses contain boron oxide, which produces a strong, chemically resistant network with a low coefficient of…
Correct answer: Heat resistant- A. More soluble in cold water
- B. More soluble in hot water
- C. Insoluble in water
- D. Soluble only in organic solvents
Explanation: Borax dissolves more readily as temperature increases, so it is more soluble in hot water than in cold water.
Correct answer: More soluble in hot water- A. Molecular addition compounds
- B. Molecular crystals
- C. Semiconductors
- D. Ionic compounds
Explanation: Boron is electron deficient because it has only three valence electrons, so it readily forms electron-accepting molecular addition…
Correct answer: Molecular addition compounds- A. Acidic
- B. Basic
- C. Acidic and basic
- D. Neutral and acidic
Explanation: An amphoteric oxide reacts with both acids and bases, showing both basic and acidic behaviour, such as Al2O3.
Correct answer: Acidic and basic- A. Acidic
- B. Amphoteric
- C. Neutral
- D. All of the above
Explanation: Non-metal oxides are usually acidic because they react with water to form acids or with bases to form salts, as SO3 forms H2SO4.
Correct answer: Acidic- A. Ethylene iodide
- B. Ethylene bromide
- C. Ethylene chloride
- D. Ethylene fluoride
Explanation: Ethylene bromide, C2H4Br2, was added to leaded petrol so that it reacted with lead compounds and helped convert deposits into volatile…
Correct answer: Ethylene bromide- A. Carbon dioxide and methane
- B. Carbon dioxide and nitric oxide
- C. Nitrogen and oxygen
- D. Water vapour and ozone
Explanation: Nitrogen and oxygen are not greenhouse gases, while carbon dioxide, methane, water vapor, and ozone are.
Correct answer: Nitrogen and oxygen- A. Be2C
- B. CaC2
- C. MgC2
- D. SrC2
Explanation: Beryllium carbide does not decompose with water to form CH4 gas. It is generally less reactive compared to calcium carbide.
Correct answer: Be2C- A. Coke, Coal tar, Coal gas
- B. Methane, Coal, Coaltar
- C. Carbon monoxide, methane, hydrogen gas
- D. Phenol, coke, hydrogen gas
Explanation: Option A is correct because it accurately represents the main products obtained from the destructive distillation of coal.
Correct answer: Coke, Coal tar, Coal gas- A. 2+,4+
- B. 1+,4+
- C. 4+,2+
- D. 2+,3+

Correct answer: 2+,4+- A. Reducing agents
- B. Oxidizing agents
- C. Dehydrating agents
- D. Hydrating agents
Explanation: Compounds containing Pb+4 ions tend to act as reducing agents. In these compounds, lead is in its highest oxidation state (+4), and it has…
Correct answer: Reducing agents- A. Hg
- B. Pb
- C. Fe
- D. As
