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.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Directions: In the following questions, a statement of assertion (A) ...
B) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

Explanation: Iso-butane is indeed an isomer of C4H10, which means it has the same molecular formula (C4H10) but a different structural arrangement of atoms. The reason given, however, is simply stating the molecular formula of iso-butane, which is not the correct explanation for it being an isomer. The correct explanation would be that iso-butane has a different structural arrangement compared to the other isomer, n-butane.

Directions: In the following questions, a statement of assertion (A) ...
Answer: b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

Explanation:

Iso-butane is an isomer of C4H10, which means it has the same chemical formula but a different molecular structure. It has four carbon atoms and ten hydrogen atoms, just like n-butane, which is another isomer of C4H10. Therefore, assertion (A) is true.

However, the reason given (R) is not the correct explanation of assertion (A). While it is true that iso-butane has four C and ten H atoms, this is also true for n-butane. The difference between the two isomers lies in their molecular structure, which affects their physical and chemical properties. Therefore, reason (R) is not a sufficient explanation for why iso-butane is an isomer of C4H10.

Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): Iso-butane is the isomer of C4H10.
Reason (R): Iso-butane has four C and ten H atoms.

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).

Explanation:

Isomers:
Isomers are compounds that have the same molecular formula but different structural arrangements or spatial orientations.

Iso-butane:
Iso-butane, also known as 2-methylpropane, is an isomer of butane. It has the molecular formula C4H10. In iso-butane, there are four carbon atoms (C) and ten hydrogen atoms (H).

Explanation of Assertion (A):
The assertion (A) states that iso-butane is the isomer of C4H10. This assertion is true because iso-butane indeed has the molecular formula C4H10.

Explanation of Reason (R):
The reason (R) states that iso-butane has four C and ten H atoms. This reason is true because iso-butane does have four carbon atoms (C) and ten hydrogen atoms (H).

Explanation of the Answer:
Both the assertion (A) and reason (R) are true. Iso-butane is indeed the isomer of C4H10, and it does have four C and ten H atoms. However, the reason (R) is not the correct explanation of the assertion (A).

Additional Information:
Iso-butane differs from normal butane (n-butane) in the arrangement of carbon atoms. In iso-butane, the four carbon atoms are arranged in a branched structure, whereas in n-butane, the carbon atoms are arranged in a straight chain. Both iso-butane and n-butane are hydrocarbons and belong to the alkane family.
