Question

Which of the following are peroxoacids of sulphur?

• A. $H_{2}S{O}_5$ and $H_2{S}_2{O}_8$
• B. $H_{2}S{O}_5$ and $H_2{S}_2{O}_7$
• C. $H_2{S}_2{O}_7$ and $H_2{S}_2{O}_8$
• D. $H_2{S}_2{O}_6$ and $H_{2}S{O}_5$

Answer 1

The correct option is A $H_{2}S{O}_5$ and $H_2{S}_2{O}_8$

Peroxy linkage means in a compound there should be bond between oxygen and oxygen ($O-O$)

In the above oxoacids of sulfur only $H_{2}S{O}_5,H_2{S}_2{O}_8$ ha spoeroxy linkage.

Hence option A is correct.
