Carbon and Its Compounds Questions and Answers
- 1.
Which of the following compounds of carbon does not consist of ions?
- A.
CHCl3
- B.
CaCO3
- C.
NaHCO3
- D.
Ca2C
Correct Answer
A. CHCl3Explanation
CHCl3 does not consist of ions because it is a covalent compound. In covalent compounds, atoms share electrons rather than transferring them to form ions. CHCl3 is formed by the sharing of electrons between carbon and hydrogen atoms, as well as between carbon and chlorine atoms, resulting in a stable molecule.Rate this question:

Which of the following bonds is very strong and hence very stable?
- A.
Carbon-Carbon bond
- B.
Carbon–Iodine bond
- C.
Carbon-Silicon bond
- D.
Carbon–Sulphur bond
Correct Answer
A. Carbon-Carbon bondExplanation
The Carbon-Carbon bond is very strong and stable because carbon atoms have a similar electronegativity, resulting in a balanced sharing of electrons between them. This bond is covalent, meaning that the carbon atoms share their outer electrons, forming a strong bond. Additionally, carbon is capable of forming multiple bonds with other carbon atoms, allowing for the formation of long chains and complex structures, further enhancing the stability of the Carbon-Carbon bond.Rate this question:

Which of the following compounds is an unsaturated hydrocarbon? i. Propane ii. Benzene iii. Acetylene
- A.
(i) and (iii)
- B.
(i) and (ii)
- C.
(iii)
- D.
(ii) and (iii)
Correct Answer
D. (ii) and (iii)Explanation
Benzene and acetylene are both unsaturated hydrocarbons. Benzene is a cyclic compound with a delocalized pi bond system, making it aromatic and unsaturated. Acetylene, also known as ethyne, is a linear compound with a triple bond between two carbon atoms, making it unsaturated as well. Propane, on the other hand, is a saturated hydrocarbon as it only contains single bonds between carbon atoms.Rate this question:

The I.U.P.A.C name of CH3CH2CH=CH2 is?
- A.
Butene
- B.
Prop-1-ene
- C.
But-1-ene
- D.
Butyne
Correct Answer
C. But-1-eneExplanation
The I.U.P.A.C name of CH3CH2CH=CH2 is But-1-ene. This is because the compound has four carbon atoms, making it a butene. The double bond is located between the first and second carbon atoms, hence the name "but-1-ene."Rate this question:

Which of the following statements about graphite and diamond is true?
- A.
They have the same crystal structure
- B.
They have the same degree of hardness
- C.
They have the same electrical conductivity
- D.
They can undergo the same chemical reactions
Correct Answer
D. They can undergo the same chemical reactionsExplanation
Graphite and diamond are both forms of carbon, but they have different crystal structures. Graphite has a layered structure, while diamond has a three-dimensional network structure. However, they can undergo the same chemical reactions because they are both composed of carbon atoms. The difference in their crystal structures affects their physical properties, such as hardness and electrical conductivity, but it does not prevent them from reacting chemically in a similar way.Rate this question:

While cooking, if the bottom of the vessel is getting blackened on the outside, it means that
- A.
The food is not cooked completely
- B.
The fuel is not burning completely
- C.
The fuel is wet
- D.
The fuel is burning completely
Correct Answer
B. The fuel is not burning completelyExplanation
If the bottom of the vessel is getting blackened on the outside while cooking, it indicates that the fuel is not burning completely. Incomplete combustion of fuel can lead to the formation of soot, which causes the vessel to become blackened. This could be due to a lack of oxygen supply or improper fuel-air mixture, resulting in inefficient burning of the fuel.Rate this question:

Homologous series is a series of compounds in which
- A.
The same functional group substitutes for hydrogen in a carbon chain
- B.
Formulae of successive compounds differ by a –CH3 – unit
- C.
Representation is possible by any formula
- D.
Is collection of compounds with different functional groups
Correct Answer
A. The same functional group substitutes for hydrogen in a carbon chainExplanation
A homologous series is a series of compounds where the same functional group substitutes for hydrogen in a carbon chain. This means that each compound in the series will have the same general structure, but with increasing chain length. For example, in the alcohol homologous series, each compound will have the general formula R-OH, where R represents a carbon chain. The only difference between each compound in the series is the length of the carbon chain.Rate this question:

Which of the following statements is true with regard to hydrogen? i. Hydrogen reacts to attain a duplet of electrons in its K shell. ii. Hydrogen always forms a single covalent bond. iii. Hydrogen can form a single and a double covalent bond.
- A.
(i)
- B.
(i) and (ii)
- C.
(i) , (ii) and (iii)
- D.
(i) and (iii)
Correct Answer
B. (i) and (ii)Explanation
Hydrogen, being in Group 1 of the periodic table, has only one electron in its outermost shell (K shell). To achieve a stable electron configuration, hydrogen typically forms one covalent bond, resulting in a duet (two electrons) in its K shell, resembling the electron configuration of helium.Rate this question:

![Carbon And Its Compounds Quiz: Trivia - Quiz]()
Correct Answer
B.Explanation
The electron dot structure of a chlorine molecule consists of two chlorine atoms, each with seven valence electrons. The correct structure is where the two chlorine atoms are connected by a single bond, and each chlorine atom has three lone pairs of electrons around it. This structure is represented by two chlorine atoms, each with three pairs of dots surrounding it, and a single line between them to indicate the bond.Rate this question:

Which of the following statements is not true? i. In the earth’s crust carbon is present in the form of minerals. ii. There is little carbon in the atmosphere iii. In the earth’s crust very large amount of carbon are present.
- A.
(i)
- B.
(i) and (iii)
- C.
(iii)
- D.
(ii) and (iii)
Correct Answer
C. (iii)Explanation
In the given question, the statement (iii) "In the earth's crust very large amounts of carbon are present" is not true. This is because carbon is not present in very large amounts in the earth's crust. While carbon is present in the form of minerals in the earth's crust (as mentioned in statement i), it is not present in large quantities. The majority of carbon on Earth is actually found in the atmosphere (as mentioned in statement ii) and in the form of fossil fuels. Therefore, statement (iii) is the correct answer as it contradicts the actual distribution of carbon in the earth's crust.Rate this question:

Two compounds ‘A’ and ‘B’ are isomers and contain only hydrogen and carbon. Which of the following statements, regarding A and B, is true? i. Both will have the same IUPAC name ii. Both will have the same structure iii. Both are hydrocarbons iv. Both have the same molecular formula
- A.
(i), (iii) and (iv)
- B.
(iii) and (iv)
- C.
(iv)
- D.
(iii)
Correct Answer
B. (iii) and (iv)Explanation
Isomers are compounds that have the same molecular formula but different structures. Therefore, statements (iii) and (iv) are true. Both compounds A and B will be hydrocarbons (only contain carbon and hydrogen) and will have the same molecular formula. However, they may have different arrangements of atoms or functional groups, resulting in different structures.Rate this question:

A cation is formed when a/an
- A.
Atom gains electrons
- B.
Atom loses electrons
- C.
Proton is lost by the atom
- D.
Atom shared by electrons
Correct Answer
B. Atom loses electronsExplanation
When an atom loses electrons, it becomes positively charged and forms a cation. This is because electrons have a negative charge, and when they are lost, the atom has more protons than electrons, resulting in a net positive charge. Therefore, the correct answer is "atom loses electrons".Rate this question:

Which of the following statements regarding alkenes is not true?
- A.
Alkenes are hydrocarbons
- B.
They are unsaturated compounds
- C.
They can consist of one or more double bonds.
- D.
The number of hydrogen atoms is always double the number of carbon atoms
Correct Answer
D. The number of hydrogen atoms is always double the number of carbon atomsExplanation
Alkenes are hydrocarbons, meaning they are composed of only carbon and hydrogen atoms. They are unsaturated compounds because they contain at least one double bond between carbon atoms. They can consist of one or more double bonds, allowing for the possibility of multiple double bonds in their structure. However, the statement that the number of hydrogen atoms is always double the number of carbon atoms is not true. The ratio of hydrogen to carbon atoms in alkenes can vary depending on the specific molecule.Rate this question:
