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 : Theaverage of four oxidation numbers of sulphurs of the S_(4)O_(6)^(2-) is 2.5.

1.	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 : Theaverage of four oxidation numbers of sulphurs of the S_(4)O_(6)^(2-) is 2.5.
Answer» If both assertion and reason are true and reason is the correct explanation of assertion. If both assertion and reason are true but reason is not the correct explanation of assertion. If assertion is true but reason is false. If both assertion and reason are false. Solution :The structure of `S_(4)O_(6)^(2-)` is `.^(-)O-underset(underset(O)("\|\|"))overset(overset(O)("\|\|+5"))("S")-overset(0)S-overset(0)S-underset(underset(O)("\|\|"))overset(overset(O)("\|\|+5"))("S")-O^(-)` Structural parameters reveal that the element for whom FRACTIONAL oxidation state is realised, is present in different oxidation STATES and differentoxidation states are DUE to different bonding situations.
