Among $NH _{3 }$, $H _{ 2 }O$ and HF, which would you expect of have highest , magnitude of hydrogen bonding and why?


#2

Since, electronegativity of F is the highest, therefore, magnitude of the positive charge on hydrogen and negative charge on F is the highest in HF and hence, electrostatic . attraction of the H-bonding is the strongest in H—F.
