Which of the following has the highest extent of hydrogen bonding? A) NH3, B)H2O c)HF

A

`NH_(3)`

B

`H_(2)O`

C

HF

D

Same in all

Text Solution

Verified by Experts

The correct Answer is:
B
Among nitrogen, fluorine and oxygen, the increasing order of electronegativities are `N lt O lt F`. Hence, `HF gt H_(2),O gt NH_(3)`,. But, the actual order is `H_(2),O gtHF gt NH_(3)`,. Although fluorine is more elect than oxygen, the extent of hydrogen bonding is higher in water
