Question

What is the oxidation number of $S$ in $H_2{S}_4{O}_6$.

• A. $-2.5$
• B. The O.N of each of the $S$ - atom linked with each other in the middle is $+5$ while that of each of the remaining two $S$ - atoms is $0$
• C. $+6$
• D. The O.N of each of the $S$ - atom linked with each other in the middle is zero while that of each of the remaining two $S$ - atoms is $+5$

Answer 1

The correct option is D The O.N of each of the $S$ - atom linked with each other in the middle is zero while that of each of the remaining two $S$ - atoms is $+5$

By chemical bonding method


The O.N of each of the $S$ - atom linked with each other in the middle is zero while that of each of the remaining two $S$ - atoms is $+5$.
