MCQ
The correct order of acidic strength is
- ✓$HF < HCl < HBr < HI$
- B$HCl < HBr < HF < HI$
- C$HBr < HCl < HI < HF$
- D$HI < HBr < HCl < HF$
✓
Answer
Correct option: A.
$HF < HCl < HBr < HI$
a
(a)$HF < HCl < HBr < HCl$
As we go down the group bond energy decreases hence, acidic nature increases.
