MCQ
In which compound, the hydrogen bonding is the strongest in its liquid phase
- ✓$HF$
- B$HI$
- C$C{H_4}$
- D$P{H_3}$
✓
Answer
Correct option: A.
$HF$
(a) Compound containing highly electronegative element $(F, O, N)$ attached to an electropositive element $(H)$ show hydrogen bonding. Fluorine $(F)$ is highly electronegative and has smaller size.
So hydrogen fluoride shows the strongest hydrogen bonding in the liquid phase.
