Question
In which pair of ions both the species contain $$S—S$$ bond?
A.
$${S_2}O_7^{2 - },{S_2}O_3^{2 - }$$
B.
$${S_4}O_6^{2 - },{S_2}O_3^{2 - }$$
C.
$${S_2}O_7^{2 - },{S_2}O_8^{2 - }$$
D.
$${S_4}O_6^{2 - },{S_2}O_7^{2 - }$$
Answer :
$${S_4}O_6^{2 - },{S_2}O_3^{2 - }$$
Solution :
$${S_4}O_6^{2 - }$$ and $${S_2}O_3^{2 - }$$ have $$S—S$$ bond
$${S_4}O_6^{2 - }$$ and $${S_2}O_3^{2 - }$$ have $$S—S$$ bond
