Among `NH_(3),H_(2)O`, and `HF`, which would you expect to have highest magnitude of hydrogen bonding and why?

Explanation

All these molecules undergo hydrogen bonding due to greater electronegativity of N, O and F.

Since F is most electronegative and therefore, the magnitude of negative charge on F and positive charge on H will be higest and thererfore, H-bonding will be strongest in HF.
