Question

Which of the following oxyacids of sulphur contain four S = 0 bonds?

पर्याय

• H₂SO₅

• H₂SO₄

• H₂S₂O₄

• H₂S₂O₆

Answer 1

H₂S₂O₆

Explanation:

H₂S₂O₆ oxyacids of sulphur contain four S = 0 bonds. It is shown as below:

\[\begin{array}{cc}
\ce{O}\phantom{...}\ce{O}\\
||\phantom{...}||\\
\ce{O = S - S = O}\\
|\phantom{....}|\\
\phantom{.....}\ce{\underset{\ce{(H2S2O6)}}{\underset{\text{Dithionic acid}}{OH\phantom{.}OH}}}
\end{array}\]
