Question

Which of the following hydrogen halide is liquid at room temperature?

(A) HF (B) HCl (C) HBr (D) HI

Answer 1

Answer:

Hydrogen Flouride (HF)

Explanation:

HF has strong hydrogen bonding, so the force between molecules is stronger for this than in other hydrogen halides.

Answer 2

      In the following hydrogen halide HF, HCl, HBr, HI given, the hydrogen fluoride (HF) becomes the liquid gas at the room temperature whereas other hydrogen halides becomes gas.

Answer - HF (Option A)

Explanation:

         The HF becomes the liquid gas because of the strong force of exertion which acts between the hydrogen H and the F fluoride, the large molecular attraction is the primary reason for the HF to become the liquid gas at the room temperature.
