Assertion: Boron exhibits anomalous behavior compared to other elements in Group 13 of the periodic table.
Reason: Boron has a small atomic size and high ionization energy, which make it difficult to exhibit typical behavior of Group 13 elements.
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion is true, but the reason is false.
The assertion is false, but the reason is true.
Answers (1)
Boron is unique among the elements of Group 13 due to its small atomic size and high ionization energy. These factors make it difficult for Boron to exhibit the typical behaviour of the group. For example, boron forms covalent compounds with hydrogen instead of the typical ionic compounds formed by other Group 13 elements. This is because the small size of the boron atom allows it to form strong covalent bonds with hydrogen, while the larger Group 13 elements cannot do so as easily. Hence option 1 is the correct answer.
Option (2) is incorrect because it incorrectly states that the assertion is correct but the reason is incorrect. Both the assertion and reason are correct. Hence option 2 is incorrect.
Option (3) 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 3 is incorrect.
Option (4) is incorrect because it incorrectly states that both the assertion and reason are incorrect. Both the assertion and reason are correct. Hence option 4 is incorrect.
