Question

Of the following hydrides, which one has the lowest boiling point? (A) Hydrogen fluoride (B) Hydrogen chloride (C) Hydrogen bromide (D) Hydrogen iodide

Tardigrade Admin · Accepted Answer

Hydrogen chloride (HCl) has the lowest boiling point among halogen acids. HF has abnormally high boiling point ( 20° C ) due to hydrogen bonding while other are gases at room temperature.

Q. Of the following hydrides, which one has the lowest boiling point?

Hydrogen fluoride

Hydrogen chloride

Hydrogen bromide
