Question

$S-S$ bond is present in the acid $H_2{S}_2{O}_3$ (thiosulphuric acid).

If true enter 1, else enter 0.

Answer 1

$H_2{S}_2{O}_3$ is a basic acid and hence, two OH groups are directly attached to the central" S" atom. The dibasic acid nature supports the (S-S) bond.

The structure of thiosulphuric acid is as follows:

So, the correct option is 1.
