Q. Assertion: The formal oxidation no. of sulphur in $N a_{2} S_{4} O_{6}$ is 2.5.
Reason: Two S-atoms are not directly linked with O-atoms.

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

Formal oxidation number of sulphur

$= \frac{2 \times 5 + 2 \times 0}{4} = 2.5$
