Assertion : In some cases oxygen shows positive oxidation number though it is an electronegative element. Reason : Fluorine is more electronegative than oxygen.
Options
- AIf both Assertion and Reason are true and Reason is the correct explanation of Assertion.
- BIf both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
- CIf Assertion is true but Reason is false.
- DIf Assertion is false but Reason is true.
Correct answer
A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Step-by-step solution
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 .
