Assertion : Number of \(\mathrm{S}-\mathrm{S}\) bonds in \(\mathrm{H}_{2} \mathrm{~S}_{\mathrm{n}} \mathrm{O}_{6}\) is \((\mathrm{n}-1)\). Reason : The formula of dithionic acid is \(\mathrm{H}_{2} \mathrm{~S}_{2} \mathrm{O}_{6}\)
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
\(\mathrm{H}_{2} \mathrm{~S}_{\mathrm{n}} \mathrm{O}_{6}\), i.e., poly sulphuric acid has \((\mathrm{n}-1) \mathrm{S}-\mathrm{S}\) bonds. So, the option (2) is correct.

3 4
4 1
Explanation:
Only \({\mathrm{\mathrm{SO}_{3}^{2-}}}\) has pyramidal geometry around the central atom as sulphur has a lone pair of electrons. Rest have tetrahedral geometry around sulphur (central atom). So, the correct option is (4).
