Boiling Points of Covalent Hydrides

Chemistry Level 2

If hydrogen bonding is NOT considered, which of the following compounds would you expect to have the highest boiling point:

H F , H C l , H B r , o r H I ? \ce{HF}, ~~\ce{HCl}, ~~\ce{HBr}, ~~\ce{or} ~~\ce{HI}?

Usually, compounds with higher molecular masses have higher boiling points, so considering that basic trend, H I HI would be expected to have the highest boiling point. However, the unusually strong intermolecular forces the hydrogen bonds create between molecules of H F HF cause its boiling point to be higher than any other group 17 hydride.

heyy the options available in the problem are diffrent from whose in options........
