Question

Assertion: Fluorine exists only in $-1$ oxidation state.
Reason: Fluorine has $2s^{2}2p^5$ configuration

• A. If both assertion and reason are true and the reason is a correct explanation of the assertion
• B. If both assertion and reason are true but reason is not a correct explanation of the assertion
• C. If the assertion is true but reason is false
• D. If both the assertion and reason are false
• E. If the assertion is false but the reason is true

Answer 1

The correct option is A If both assertion and reason are true and the reason is a correct explanation of the assertion

The atomic number of flourine is 9 with electronic configuration:$\left[He\right]{2s}^2{2p}^5$

p orbital can hold only 6 electrons.

Flourine already has 5 electrons and has their is vacency for only 1 electrons.

Hence, it can accpt only 1 electron.

So. oxidation state is -1.
