What is the trend of boiling points of hydrides of N, O and F?
A
Due to lower molecular masses 
and HF have lower boiling points than those of the subsequent group member hydrides.
and HF have lower boiling points than those of the subsequent group member hydrides.
B
Due to higher electronegativity of N, O and F; 
and HF show hydrogen bonding and hence higher boiling points than the hydrides of their subsequent group members.
and HF show hydrogen bonding and hence higher boiling points than the hydrides of their subsequent group members.
C
There is no regular trend in the boiling points of hydrides.
D
Due to higher oxidation states of N, O and F, the boiling points of 
and HF are higher than the hydrides of their subsequent group members.
and HF are higher than the hydrides of their subsequent group members.
Text Solution
Verified by ExpertsThe correct answer is:
B
: Due to higher electronegativity the extent of hydrogen bonding is quite appreciable.
