Assertion : Caro's acid has \({\text{S}}\) atom in +6 oxidation state. Reason : Caro's acid contains one peroxo \(\mathrm{O}_{2}^{2-}\) group.
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:
This can be explained through structure of caro's acid (peroxomonosulphuric acid). Oxidation no. of \(\mathrm{S}=\mathrm{x}\), oxidation no. of \(\mathrm{H}=+1\), Oxidation no. of \(\mathrm{O}\) in peroxo linkage \(=-1\) (each), Oxidation no. of other oxygen atoms \(=-2\) (each). \(2+\mathrm{x}-6-2=0\) or \(\mathrm{x}=+6\) So option (1) is correct.

Which of the following statement is correct for oleum?
1 It is prepared by absorption of \(\mathrm{SO}_{3}\) in conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\)
2 It contains \(\mathrm{O}-\mathrm{O}\) groups
3 It has six \(\mathrm{OH}\) groups
4 None of the above
Explanation:
Oleum, i.e. \(\mathrm{H}_{2} \mathrm{~S}_{2} \mathrm{O}_{7}\) can be prepared by absorption of \(\mathrm{SO}_{3}\) in conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\) as follows: \(\mathrm{SO}_{3}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \underset{\text { Oleum }}{\mathrm{H}_{2} \mathrm{~S}_{2} \mathrm{O}_{7}}\) It's structure is as follows: Thus, it has no \(\mathrm{O}-\mathrm{O}\) bond and has \(2-\mathrm{OH}\) groups. Thus, option (1) is correct.
