Among `NH_(3),H_(2)O`, and `HF`, which would you expect to have highest magnitude of hydrogen bonding and why?

A

HF due to maximum polarity.

B

`H_(2)O` due to lone pairs of electrons.

C

`NH_(3)` due to small size of nitrogen.

D

`H_(2)S` due to higher electron affinity of sulphur.

Text Solution

Verified by Experts

The correct Answer is:
A
Since H - F bond has maximum polarity due to most electronegative nature of fluorine, hydrogen bonding is maximum in HF molecules.
