Question

Count the total number of $X-O$ bonds having equal length in $HSO{{}_4}^{-}$ and $S_{3}O{{}_6}^{2-}$ respectively. (If the answer is 5 and 3 then represent as 53).

• A. $36$
• B. $40$
• C. $42$
• D. $44$

Answer 1

The correct option is A $36$

In $HS{O}_4^{-}$, $3$ equal bond length are present due to resonance and in $S_3{O}_6^{2-}$, 6 equal $S-O$ bond length are present due to resonance.
