Assertion & Reason Test: Carbon & Its compounds - 2 - Question 5

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion (A): Acetic acid has six single bonds and one double bond.

Reason (R): It is an unsaturated organic compound.

Detailed Solution for Assertion & Reason Test: Carbon & Its compounds - 2 - Question 5

To determine the correctness of the given assertion and reason, let's analyze each statement separately.
Assertion (A): Acetic acid has six single bonds and one double bond.
The molecular formula of acetic acid is CH3COOH. Let's count the number of bonds in the molecule:
- Carbon (C) has four single bonds.
- Hydrogen (H) has one single bond.
- Oxygen (O) has two single bonds and one double bond.
Hence, the total number of single bonds in acetic acid is 4 + 1 + 2 = 7, and it also has one double bond.
Reason (R): It is an unsaturated organic compound.
An unsaturated compound is one that contains double or triple bonds between its carbon atoms.
From the analysis of the molecular formula of acetic acid, we can see that it contains a double bond between one of the oxygen atoms and the carbon atom. Therefore, acetic acid is indeed an unsaturated organic compound.
Now, let's evaluate the given options:
A: Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
- This option is incorrect because the reason does not provide an explanation for the assertion. The reason only states a characteristic of unsaturated compounds, but it does not explain why acetic acid specifically has six single bonds and one double bond.
B: Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
- This option is correct. Both the assertion and reason are true, but the reason does not fully explain why acetic acid has six single bonds and one double bond. The reason only states that acetic acid is an unsaturated compound, which is a characteristic of compounds with double or triple bonds.
C: Assertion (A) is true but reason (R) is false.
- This option is incorrect because both the assertion and reason are true.
D: Assertion (A) is false but reason (R) is true.
- This option is incorrect because the assertion is true. Acetic acid does have six single bonds and one double bond.
Therefore, the correct answer is option B: Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
Assertion & Reason Test: Carbon & Its compounds - 2 - Question 6

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion (A) : Iso-butane is the isomer of C4H10.

Reason (R) : Iso-butane has four C and ten-H atoms.

Detailed Solution for Assertion & Reason Test: Carbon & Its compounds - 2 - Question 6
Assertion (A) : Iso-butane is the isomer of C4H10.
Reason (R) : Iso-butane has four C and ten-H atoms.
To determine the correctness of the given assertion and reason, we need to evaluate each statement separately.
Assertion (A): Iso-butane is the isomer of C4H10.
- Iso-butane is an isomer of butane, which means they have the same molecular formula but different structural arrangements.
- The molecular formula of butane is C4H10.
- Therefore, the assertion (A) is true.
Reason (R): Iso-butane has four C and ten-H atoms.
- Iso-butane, also known as 2-methylpropane, has the molecular formula C4H10.
- It consists of four carbon (C) atoms and ten hydrogen (H) atoms.
- Therefore, the reason (R) is true.
Based on the evaluation of each statement, we can conclude that:
Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
The reason provided does not explain why iso-butane is the isomer of C4H10. It only states the number of carbon and hydrogen atoms in iso-butane, which is the same as the molecular formula of butane. However, it does not provide an explanation for the isomeric relationship between the two compounds.
Assertion & Reason Test: Carbon & Its compounds - 2 - Question 7

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Cyclopropane is a heterocyclic compound.

Reason : Cyclopropane comes into the category of those compounds in which a complete ring is formed by carbon atoms only.

Detailed Solution for Assertion & Reason Test: Carbon & Its compounds - 2 - Question 7
Cyclopropane is a homocyclic compound in which the ring is made up of carbon atoms only.
Assertion & Reason Test: Carbon & Its compounds - 2 - Question 8

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Carbon has the ability to form long carbon chains.

Reason : Carbon has a unique property of ability to form long straight and branched chains called catenation.

Detailed Solution for Assertion & Reason Test: Carbon & Its compounds - 2 - Question 8
Catenation can be defined as the self-linking of atoms of an element to form chains and rings and it can also be defined or we can say that this definition can be extended by mentioning that it can also form layers like two-dimensional catenation and space lattices like three-dimensional catenation. Catenation generally occurs in carbon because carbon forms covalent bonds to form longer chains and structures with other carbon atoms. Carbon is best known for its catenation properties with the analysis of catenated carbon structures in organic chemistry.

- Hence from the above discussion we can conclude that option A is the correct answer i.e. carbon has the ability to form long carbon chains and this property is explained on the basis of catenation.

So, the correct answer is “Option A”.

Assertion & Reason Test: Carbon & Its compounds - 2 - Question 9

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Propene reacts with HBr to give isopropyl bromide.

Reason : Addition of Br2 to alkene places faster in presence of ionising substance.

Detailed Solution for Assertion & Reason Test: Carbon & Its compounds - 2 - Question 9
Explanation:
The given assertion and reason can be analyzed as follows:
Assertion (A): Propene reacts with HBr to give isopropyl bromide.
Reason (R): Addition of Br2 to alkene places faster in the presence of an ionizing substance.
To determine the correctness of the assertion and reason, we need to evaluate each statement individually:
Evaluation of Assertion (A):
Propene is an alkene with the molecular formula C3H6. HBr (hydrogen bromide) is an electrophilic reagent that can add to the double bond of an alkene. This addition reaction replaces one of the hydrogen atoms of propene with a bromine atom, resulting in the formation of isopropyl bromide (2-bromopropane). Therefore, the assertion is true.
Evaluation of Reason (R):
The reason states that the addition of Br2 to an alkene occurs faster in the presence of an ionizing substance. However, the given assertion does not involve the addition of Br2 to an alkene. It only involves the addition of HBr to propene. Therefore, the reason is not applicable to the given assertion and is false.
Based on the evaluation of the assertion and reason, we can conclude that:
- Assertion (A) is true because propene reacts with HBr to give isopropyl bromide.
- Reason (R) is false because it does not explain the given assertion.
Hence, the correct answer is option B: Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
Assertion & Reason Test: Carbon & Its compounds - 2 - Question 10

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion : Carbon compounds can form chain, branched and ring structures.

Reason : Carbon exhibits the property of catenation.

Detailed Solution for Assertion & Reason Test: Carbon & Its compounds - 2 - Question 10
Assertion and Reason:

Assertion: Carbon compounds can form chain, branched, and ring structures.


Reason: Carbon exhibits the property of catenation.



The given statement involves an assertion and a reason. Let's analyze the assertion and reason individually to determine their validity.


Assertion: Carbon compounds can form chain, branched, and ring structures.
- This assertion is true. Carbon is unique because it can form covalent bonds with other carbon atoms, allowing for the formation of long chains, branched structures, and closed rings. This property is known as catenation.
Reason: Carbon exhibits the property of catenation.
- This reason is also true. Catenation is the ability of an element, particularly carbon, to form covalent bonds with other atoms of the same element. Carbon has four valence electrons, allowing it to form up to four covalent bonds. This property of carbon enables the formation of various structures, including chains, branches, and rings.
Conclusion:
Both the assertion and the reason are true. Furthermore, the reason (carbon's catenation property) provides a correct explanation for the assertion (formation of chain, branched, and ring structures). Therefore, option A is the correct answer.
Note: The key here is to understand that carbon's ability to form covalent bonds with other carbon atoms is what allows for the formation of different structures. This property is known as catenation, and it is the reason behind carbon compounds' versatility in forming chains, branches, and rings.
