MCQ
Which of the hydrogen halides forms salts like $KH{X_2}$ (where $X$ is a halogen atom)
- ✓$HF$
- B$HCl$
- C$HI$
- D$HBr$
✓
Answer
Correct option: A.
$HF$
a
(a) Due to highest electronegativity of fluorine the anion ${[F - - - H - F]^ - }$ exists as a result of strong hydrogen bond by which ${K^ + }$ associate to form $KH{F_2}$.
