Question:
Which of the following hydrogen bonds are strongest in vapour phase?
Which of the following hydrogen bonds are strongest in vapour phase?
Show Hint
HF exhibits the strongest hydrogen bonds because fluorine is highly electronegative.

- HF . . . HF
- HF . . . HI
- HCl . . . HCl
- HF . . . HI
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Hydrogen bonds are strongest when the hydrogen is bonded to a highly electronegative atom like fluorine. The HF . . . HF interaction is the strongest in the vapour phase.
