MCQ
Which among the following is strongest acid
- A$H(ClO)O_2$
- ✓$H(ClO)O_3$
- C$H(ClO)O$
- D$H(ClO)$
✓
Answer
Correct option: B.
$H(ClO)O_3$
(b)For oxoacids of the same element, the acidic strength increases with increase in the oxidation number of that element.
$\mathop {HClO}\limits^{ + 1} < \mathop {HCl{O_2}}\limits^{ + 3} < \mathop {HCl{O_3}}\limits^{ + 5} < \mathop {HCl{O_4}}\limits^{ + 7} $
$\mathop {HClO}\limits^{ + 1} < \mathop {HCl{O_2}}\limits^{ + 3} < \mathop {HCl{O_3}}\limits^{ + 5} < \mathop {HCl{O_4}}\limits^{ + 7} $
