The variation of the boiling point of the hydrogen halides is in the order HF > HI > HBr > HCl.
The higher boiling point of hydrogen fluoride is explained as:
| 1. | The electronegativity of flourine is much higher than other elements in group |
| 2. | There is strong hydrogen bonding between HF molecules |
| 3. | The bond energy of HF molecules is greater than in other hydrogen halides |
| 4. | The effect of nuclear shielding is much reduced in flourine which polarizes the HF molecule |

In the light of the below statements, choose the correct answer from the options given below:
| Statement I: | Acid strength increases in the order given as HF < HCl < HBr < HI. |
| Statement II: | As the size of the elements F, Cl, Br, I increases down the group, the bond strength of HF, HCI, HBr, and HI decreases and so the acid strength increases. |
| 1. | Statement I is correct and Statement II is incorrect |
| 2. | Statement I is incorrect and Statement II is correct. |
| 3. | Both Statement I and Statement II are correct. |
| 4. | Both Statement I and Statement II are incorrect. |
