हिन्दीWhich of the following represents the correct increasing order of acid strength for hydrogen halides?
Correct answer · Option 4
\( \text{HF} < \text{HCl} < \text{HBr} < \text{HI} \)
Explanation
Down the group, halogen size increases so the H-A bond strength decreases, causing acid strength to increase: \( \text{HF} < \text{HCl} < \text{HBr} < \text{HI} \).
