A) \[{{H}_{2}}{{S}_{2}}{{O}_{4}}\]
B) \[{{H}_{2}}{{S}_{2}}{{O}_{6}}\]
C) \[{{H}_{2}}{{S}_{2}}{{O}_{8}}\]
D) None of these
Correct Answer: C
Solution :
Key Idea: Draw structure of all compounds to find which of them does not have S-S bond. \[\underset{\text{hyposulphurous}\,\text{acid}}{\mathop{\underset{(a)}{\mathop{\underset{{{H}_{2}}{{S}_{2}}{{O}_{4}}}{\mathop{H-O-\overset{O}{\mathop{\overset{||}{\mathop{S}}\,}}\,-\overset{O}{\mathop{\overset{||}{\mathop{S}}\,}}\,-O-H}}\,}}\,}}\,\] \[\underset{dithionic\,acid}{\mathop{\underset{(b)}{\mathop{\underset{{{H}_{2}}{{S}_{2}}{{O}_{6}}}{\mathop{H-O-\underset{O}{\overset{O}{\mathop{\underset{||}{\overset{||}{\mathop{S}}}\,}}}\,-\underset{O}{\overset{O}{\mathop{\underset{||}{\overset{||}{\mathop{S}}}\,}}}\,-O-H}}\,}}\,}}\,\] \[\underset{\text{Marshall }\!\!\!\!\text{ s}\,\text{acid}}{\mathop{\underset{(c)}{\mathop{\underset{{{H}_{2}}{{S}_{2}}{{O}_{8}}}{\mathop{H-O-\underset{O}{\overset{O}{\mathop{\underset{||}{\overset{||}{\mathop{S}}}\,}}}\,-O-O-\underset{O}{\overset{O}{\mathop{\underset{||}{\overset{||}{\mathop{S}}}\,}}}\,-O-H}}\,}}\,}}\,\] \[\therefore \]Marshalls acid does not have \[S-S\]bond.
