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.
