JEE Main levelSingle correct optionDifficulty 2 of 3bn138

Assertion: The oxidation number of oxygen in $OF X_{2}$ is $+ 2$ . Reason: Fluorine is more electronegative than oxygen and is always assigned $- 1$ .

ABoth the Assertion and the Reason are true, and the Reason is the correct explanation of the Assertion
BBoth the Assertion and the Reason are true, but the Reason is not the correct explanation of the Assertion
CThe Assertion is true but the Reason is false
DThe Assertion is false but the Reason is true

Answer: A

F is

- 1

always, so

x + 2 (- 1) = 0

gives O

= + 2

. This occurs because F is more electronegative than O, so the Reason explains the Assertion.
