Question

Assertion :The formal oxidation no. of sulphur in Na2S4O6 is 2.5. Reason: Two S atoms are not directly linked with O atoms.
  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Both Assertion and Reason are incorrect

A
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B
Both Assertion and Reason are incorrect
C
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
D
Assertion is correct but Reason is incorrect
Solution
Verified by Toppr

The formal oxidation number of sulphur in the given compound will be

=(2×5)+(2×0)4=2.5

Since in the structure, S atoms are not directly linked we get that oxidation state.

Hence option A is correct.
