Which of the following are peroxoacids of sulphur?
विकल्प
\[\ce{H2SO5 and H2S2O8}\]
\[\ce{H2SO5 and H2S2O7}\]
\[\ce{H2S2O7 and H2S2O8}\]
\[\ce{H2S2O6 and H2S2O7}\]
उत्तर
\[\ce{H2SO5 and H2S2O8}\]
Explanation:
Peroxy linkage refers to the presence of a bond between oxygen and oxygen (O – O) in a molecule.
Only \[\ce{H2SO5 and H2S2O7}\] of the sulphur oxoacids above have a peroxy linkage.
\[\begin{array}{cc}
\ce{O}\phantom{.....}\\
||\phantom{.....}\\
\ce{HO - S - O - OH}\\
||\phantom{.....}\\
\ce{O}\phantom{.....}
\end{array}\]
\[\begin{array}{cc}
\phantom{.}\ce{O}\phantom{.......}\ce{O}\phantom{.....}\\
\phantom{.}||\phantom{........}||\phantom{.....}\\
\ce{HO - S - O - O - S - OH}\\
\phantom{.}||\phantom{........}||\phantom{.....}\\
\phantom{.}\ce{O}\phantom{........}\ce{O}\phantom{.....}
\end{array}\]
