Arrange NH_3,H_2O and HF in the order of increasing magnitude of hydro

1.	Arrange NH_3,H_2O and HF in the order of increasing magnitude of hydrogen bonding and explain the basis for your arrangement.
Answer» SOLUTION : (i) Increasing magnitude of hydrogen BONDING among `NH_(3)`, `H_(2)O` and HF is `HF>H_(2)O>NH_(3)` (II) The extent of hydrogen bonding depends upon electronegativity and the number of hydrogen atoms available for bonding. (iii) Among N, F and the increasing order of their ELECTRONEGATIVITIES are N(iv) HENCE the expected order of the extent of hydrogen bonding is `HF>H_(2)O>NH_(3)`.
