Which of the following are peroxoacids of sulphur?

1.	\(\mathrm{H_{2} SO_{5} } \text{ and } \mathrm{H_{2} S_{2} O_{8}}\)	2.	\(\mathrm{H_{2} SO_{5 }} \text{ and } \mathrm{H_{2} S_{2} O_{7}}\)
3.	\(\mathrm{H_{2} S_{2} O_{7}} \text{ and } \mathrm{H_{2} S_{2} O_{8}}\)	4.	\(\mathrm{H_{2} S_{2} O_{6}} \text{ and } \mathrm{H_{2} S_{2} O_{7}}\)

Hint: Peroxoacid contains -O-O- linkage.

Peroxoacids of sulphur must contain one -O-O- linkage.

H_{2} {SO}_{5} and H_{2} S_{2} O_{8}

are the compound that contains a peroxy linkage. The structures of both the compound are as follows:

The structures of the other compounds are as follows:
