Question

Predict the type of linkage in $H_{2}S{O}_5$.

• A. Oxy linkage
• B. Peroxy linkage
• C. Direct linkage between central atom
• D. None of the above

Answer 1

The correct option is B Peroxy linkage

Consider the oxidation state of S as 'x' in $H_{2}S{O}_5$
$\therefore x+5\times (-2)+2=0$
$\Rightarrow x=+8$
Thus calculated oxidation state of S = +8
Maximum oxidation of sulphur = number of valence electron = +6
$\because$ Oxidation state of S > maximum oxidation of sulphur
$\therefore$ Peroxy bond is present in $H_{2}S{O}_5$
