Assertion: Boron does not form a stable compound with oxygen.
Reason: Boron has a smaller size and higher electronegativity than oxygen.
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.
The Assertion is true because boron does not form a stable compound with oxygen due to its small size and high electronegativity, which makes it difficult for boron to attract electrons from oxygen to form a stable compound. The Reasoning is also true because boron has a smaller size and higher electronegativity than oxygen, which makes it difficult for them to form stable compounds.Hence option A is the correct answer.
Option(2) Both assertion and reason are true and the reason explains assertion correctly. Hence option 2 is incorrect.
Option(3) Both assertion and reason are true. Hence option 3 is incorrect.
Option(4) Both assertion and reason are true. Hence option 4 is incorrect.
