Among NH3, H2O and HF, which would you expect to have the highest magnitude of hydrogen bonding and why ?
Electronegativity of N, O F increases as N < O < F.
Therefore strength of hydrogen bond also increases as
N - H ... N < O - H ... O < F - H ... F
In other words, the magnitude of the +ve charge on hydrogen and -ve charge on F is highest and hence electrostatic attraction or hydrogen bonding is strongest in H – F.
Would you expect the hydrides of N, O and F to have lower boiling points than the hydrides of their subsequent group members? Give reasons.
