Answers (1)

best_answer

As we have learnt,

Boiling point of Halogen hydride

HF>HI>HBr>HCl
 
It is to be noted that the boiling point depends upon the molecular mass as well as the intermolecular force of attraction between the molecules

Here, in this case due to the very strong Hydrogen bonding in HF, the boiling point of HF is higher than HI.

Therefore, option (2) is correct.
