Question

Assertion : In some cases oxygen shows positive oxidation number though it is an electronegative element.
Reason : Fluorine is more electronegative than oxygen.

• A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. If Assertion is true but Reason is false
• D. If Assertion is false but Reason is true

Answer 1

Answer: (A)

Oxygen is the most electronegative element after fluorine. Therefore, in the compounds between oxygen and fluorine, oxygen is found to show positive oxidation state.

e.g. $OF_2$ : Oxygen difluoride.

Oxidation state of oxygen here is $+2$.
