The variation of the boiling points of the hydrogen halides is in the order $\mathrm{H}\mathrm{F}>\mathrm{H}\mathrm{I}>\mathrm{H}\mathrm{B}\mathrm{r}>\mathrm{H}\mathrm{C}\mathrm{l}$ . Which of the following option explains the higher boiling point of hydrogen fluoride?

• A

  The electronegativity of fluorine is much higher than for other elements in the group.
• Correct answer
  B

  There is strong hydrogen bonding between $\text{HF}$ molecules.
• C

  The bond energy of $\text{HF}$ molecules is greater than in other hydrogen halides.
• D

  The effect of nuclear shielding is much reduced in fluorine which polarizes the $\text{HF}$ molecule.

Hence, the correct answer is option: 'B'.
