Answer:
On the basis of molecular masses of \[N{{H}_{3}},{{H}_{2}}O\]and
HP, boiling point of these hydrides is expected to be lower than the hydrides
of subsequent group members. However, due to high electro negativity of nitrogen,
oxygen and fluorine, their hydrides form strong intermolecular hydrogen bond
and hence they have boiling point higher than the hydrides of subsequent group members.
