In the following question, a statement of assertion is followed by a statement of reason.Mark the correct option:
A: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
B: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
C: The assertion is true, but the reason is false.
D: The assertion is false, but the reason is true.
Assertion: The boiling points of the Group 17 elements increase down the group.
Reason: The boiling points of the Group 17 elements increase due to the increase in atomic radius down the group.
A
B
C
D
The assertion is true as the boiling points of the Group 17 elements increase down the group. However, the reason is not entirely correct, as the increase in boiling point down the group is mainly due to the increase in London dispersion forces resulting from the increase in atomic size, rather than just the increase in atomic radius. Hence option B is the correct answer.
Option (A) is incorrect because it incorrectly states that the assertion and reason are true, and the reason is the correct explanation of the assertion. Hence option A is incorrect.
Option (C) is incorrect because it incorrectly states that the assertion is incorrect but the reason is correct. The assertion is correct, and the reason is also correct. Hence option C is incorrect.
Option (D) is incorrect because it incorrectly states that both the assertion and reason are incorrect. Both the assertion and reason are correct. Hence option D is incorrect.
