Question

Write the thermal stability order of hydrogen halides

Answer 1

Hello dear ☺

Here's the answer ⤵

《 Hydrogen Halides 》

Halides are all gases with the following properties:

• Thermal reactivity decreases down the group.

• HF is the most stable to heat.
In solution the halide ions act as reducing agents, the strongest ability increases down the group.

• HI is the strongest reducing agent.

Hope it helps ✌
