What is the trend of boiling points of hydrides of N, O and F ?

A

Due to lower molecular masses `NH_(3), H_(2)O` and HF have lower boiling points than those of the subsequent group member hydrides.

B

Due to higher electronegativity of N, O and F, `NH_(3), H_(2)O` 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 `NH_(3), H_(2)O` and HF are higher than the hydrides of their subsequent group members.

Text Solution

Verified by Experts

The correct Answer is:
B
Due to higher electronegativity, the extent of hydrogen bonding is quite appreaciable.

Give correct order of boiling point of hydride of group 17.

Fifth group elements form hydrides to type AH_(3) . The hydrides have a lone pair of electrons. The hydries are reducing in nature and the reducing power is related to the stability of A-H bonds. The hydrides are covalent and low boiling. Their boiling points depends on their ability to from hydrogen bond and their molecular size which decide the intermolcular forces in the hydrides . The boiling points of the hydrides of V-group elements are in the order :
