1.	The variation of the boiling points of the hydrogen halides is in the order HPgt HI gt HBr gt HCl. What explains the higher boiling point of hydrogen fluoride?
Answer» The bond energy of HF molecules is greater than in other hydrogen halides. The effect of NUCLEAR shielding is MUCH REDUCED in fluorine which polarises the HF MOLECULE. The electronegat:ivity of fluorine is much higher than for other elements in the group There is strong hydrogen bonding between HF molecules. Solution :There is strong hydrogen bonding between HF molecules. Due to strong H-bonding HF molecule, boiling point is highest for HF :`HF gt HI gt HBR gt HI`
