315147 Fluorine does not show positive oxidation state due to the

1 Absence of s-orbitals
2 Absence of p-orbitals
3 Absence of d-orbitals
4 Highest electronegativity
CHXI08:REDOX REACTIONS

315148 Assertion :
The oxidation number of \(\mathrm{O}\) in \(\mathrm{O}_{3}\) is zero and the oxidation number of \(\mathrm{S}\) in \(\mathrm{SO}_{2}\) is +4 .
Reason :
\(\mathrm{O}_{3}\) can act as an oxidising agent as well as a reducing agent but \(\mathrm{SO}_{2}\) can act only as an oxidising agent.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
