the boiling points of NH3 , H2O and HF are exceptionally higher.explain in short.

Hi,


The first element of the group is usually small in size and is highly electronegative. Owing to this fact, the first element of these groups undergo hydrogen bonding which makes the boiling point of these compounds exceptionally higher.

 as they are ionic bonds they have high force of attraction and more energy is needed to break this force so their BP's r high 

i think
