Vedclass · Answer

(A) In Structure $1$ ($H_2S_2O_4$,dithionous acid),both sulfur atoms are in the $+3$ oxidation state. In Structure $2$ ($H_2S_2O_5$,disulfurous acid),one sulfur atom is in the $+5$ oxidation state and the other is in the $+3$ oxidation state. An increase in the oxidation state of an atom leads to a decrease in its covalent radius due to a higher effective nuclear charge. Therefore,the $S-S$ bond length $y$ in Structure $2$ is shorter than the $S-S$ bond length $x$ in Structure $1$ because of the higher oxidation state of the sulfur atom in Structure $2$. Thus,$x > y$.
