Assertion: Boron exhibits a wide range of oxidation states, including negative and fractional oxidation states.
Reason: The small size of the boron atom and its high electronegativity make it easy to form a variety of covalent bonds and oxidation states.
Reason: The small size of the boron atom and its high electronegativity make it easy to form a variety of covalent bonds and oxidation states.
View answer and explanation
Correct option: A
Both Assertion and Reason are true and Reason is the correct explanation for Assertion
The correct answer is A (Both Assertion and Reason are true and Reason is the correct explanation for Assertion) because boron's small size and high electronegativity allow for back bonding, influencing its oxidation states.
