NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyThe 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 |
