The structure of S4O62- is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/dd5ae0cc43528ac0c39301a4e6a84b1b-.png" /> Structural 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.

Q. 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.
Reason : The average of four oxidation numbers of sulphurs of the $S_{4} O_{6}^{2 -}$ is $2.5$ .
