Which of the following has the strongest H - bond?

A

`O - H ………S`

B

`S - H …….O`

C

`F - H …….F`

D

`F - H ………..O`

Text Solution

Verified by Experts

The correct Answer is:
C
The strongest hydrogen bond is in hydrogen fluoride because the power of hydrogen bond `prop` electronegativity of atom and electronegativity `prop 1/(" atomic size")`
So fluorine has maximum electronegativity and minimum atomic size.
