Read the assertion and reason carefully to mark the correct option out of the options given :–
Assertion : Caro's acid has S atom in +6 oxidation state.
Reason : Caro's acid contains one peroxo `O_2^(2–)` group.
| A. |
If both assertion and reason are true and the reason is the correct explanaton of the assertion. |
 |
| B. |
If both assertion and reason are true and the reason is not the correct explanaton of the assertion. |
| C. |
If assertion is true but reason is false. |
| D. |
If both assertion and reason are false |
Both assertion and reason are true and reason is the correct explanation of assertion.
This can be explained through the structure of Caro's acid (peroxomonosulphuric acid). Oxidation no. of S = x, oxidation no. of H = +1 Oxidation no. of oxygen in peroxo linkage = –1 Oxidation no. of other oxygen atoms= –2(each) 2 + x – 6 – 2 = 0 or x = + 6.
