For the following oxo acids, choose the increasing order of their acidity :
(A) \(HCIO < HCIO_2 < HClO_4 < HClO_3\)
(B) \(HClO_4 < HCIO_2 < HClO_3 < HCIO\)
(C) \(HClO_3 < HClO_4 < HCIO_2 < HCIO\)
(D) \(HCIO < HCIO_2 < HClO_3 < HClO_4\)
Choose the correct answer from the options given below :v
- A (A)
- B (D)
- C (C)
- D (B)
Answer & Solution
Correct Answer
(D) (B)
Step-by-step Solution
Detailed explanation
Acidity \(\propto\) oxidation state of Cl. Cl oxidation states: \(HClO (+1), HClO_2 (+3), HClO_3 (+5), HClO_4 (+7)\). Increasing order of acidity: \(HCIO < HCIO_2 < HClO_3 < HClO_4\).
