ReasonThe average of four oxidation numbers of sulphurs of the S-4-O-2-6- is 2-5-AssertionIn the species- S-4-O-6-2- each of the two extreme sulphurs exhibits oxidation state of -5 and the two middle sulphurs as zero-

Question

Correct option is B- Both Assertion and Reason are correct but Reason is not the correct explanation for AssertionStructural parameters reveal that the element for whom fractional oxidation state is realised- is present in different oxidation states and different oxidation states are due to different bonding situations-

ReasonThe average of four oxidation numbers of sulphurs of the $$S_{4}O_{2-}^{6}$$ is $$2.5.$$.AssertionIn the species, $$S_{4}O_{6}^{2-}$$ each of the two extreme sulphurs exhibits oxidation state of $$+5$$ and the two middle sulphurs as zero.

Reason
The average of four oxidation numbers of sulphurs of the $$S_{4}O_{2-}^{6}$$ is $$2.5.$$.
Assertion
In the species, $$S_{4}O_{6}^{2-}$$ each of the two extreme sulphurs exhibits oxidation state of $$+5$$ and the two middle sulphurs as zero.
