Q. Among $NH_3$, $H_2O$, $HF$ and $H_2S$ which would have highest magnitude of hydrogen bonding?
Hydrogen
A
$HF$ due to maximum polarity
41%
B
$H_2O$ due to lone pairs of electrons
28%
C
$NH_3$ due to small size of nitrogen
11%
D
$H_2S$ due to higher electron affinity of sulphur
20%
Solution:
Since $H - F$ bond has maximum polarity due to most electronegative nature of fluorine, hydrogen bonding is maximum in $HF$ molecules.
