Which of the following hydrogen bonds is the strongest?

Options

  1. AO - H N
  2. BF - H F
  3. CO - H . O
  4. DO - H F

Correct answer

B. F - H F

Step-by-step solution

The hydrogen bond in HF is strongest, because fluorine is the most electronegative element. Thus, (B) is the correct option.
