उत्तर
(i) S – S bond is present in \[\ce{H2S2O6}\].
(ii) In peroxosulphuric acid \[\ce{(H2SO5)}\] sulphur is in +6 oxidation state.
Explanation:
\[\begin{array}{cc}
\ce{O}\phantom{...}\ce{O}\\
||\phantom{...}||\\
\underset{//\phantom{...}|\phantom{........}|\phantom{...}\backslash\backslash}{\ce{S}-\ce{S}}\\
\ce{O}\phantom{..}\ce{OH}\phantom{.}\ce{OH}\phantom{.}\ce{O}
\end{array}\]
In \[\ce{H2SO5}\], there is a peroxo-linkage.
(O in peroxide linkage has oxidation state – 1)
