Question

Which of the following does not have S-S linkage?
a.) \[{{S}_{2}}O_{8}^{2-}\]
b.) \[{{S}_{2}}O_{6}^{2-}\]
c.) \[{{S}_{2}}O_{5}^{2-}\]
d.) \[{{S}_{2}}O_{3}^{2-}\]

Answer 1

Hint: S-S linkage, it means the compound should contain a bond between two sulphur atoms. To know about the S-S linkage we should know the structure of the compounds. The oxides of the sulphur contain S-S linkage.

Complete step by step answer:
All the compounds which are present in the given question are the oxides of sulphur.
The compound in option A is \[{{S}_{2}}O_{8}^{2-}\]. The structure of \[{{S}_{2}}O_{8}^{2-}\] is as follows.

In the above structure we can see that there is no bond between two sulphur atoms (S-S linkage) clearly. So, \[{{S}_{2}}O_{8}^{2-}\]does not contain S-S linkage.

Coming to option B,\[{{S}_{2}}O_{6}^{2-}\]. The structure of \[{{S}_{2}}O_{6}^{2-}\] is as follows

In the above structure there is an S-S linkage (bond between sulphur atoms), we can see it clearly.

Coming to option C, \[{{S}_{2}}O_{5}^{2-}\]. The structure of \[{{S}_{2}}O_{5}^{2-}\]is as follows

In the above structure there is an S-S linkage (bond between sulphur atoms), we can see it clearly.


Coming to option D, \[{{S}_{2}}O_{3}^{2-}\]. The structure of \[{{S}_{2}}O_{3}^{2-}\] is as follows.

In the above structure there is an S-S linkage (bond between sulphur atoms), we can see it clearly.
Therefore, the compound that does not contain S-S linkage is \[{{S}_{2}}O_{8}^{2-}\].
So, the correct answer is “Option A”.

Note:To know about the presence of S-S linkage in any compound we have to draw the structure of the compounds. If we are not going to draw the structures then we cannot say the presence of S-S linkage.
