The hydrogen bond is the strongest in

A

`O-H…..N`

B

`O-H……S`

C

`F-H…….F`

D

`F-H…….O`

Text Solution

Verified by Experts

The correct Answer is:
C
Since F is the most electronegative element, H atom attached to F is the most electron deficient. Due to the highest electronegativity, the lone pair on F attracts this `H^(delta+)` very strongly. Thus `F-H…….F` is the strongest H bond.
