Question

The correct order of the thermal stability of hydrogen halides
(H–X) is
(a) HI > HCl < HF > HBr (b) HCl< HF > HBr < HI
(c) HF > HCl > HBr > HI (d) HI < HBr > HCl < HF

Answer 1

Answer:

option (b)

Explanation:

hope it helps........

Answer 2

HF > HCl > HBr > HI is the correct order of the thermal stability of hydrogen halides.

Explanation:

• In this group, changes occur in the HX from negative to positive.
• HF is stable thermally and HI is not stable thermally.

• Thermal reactivity lower down the group. The more stable element to heat is HF. the bond energy is high so it is a weak acid.in this solution the halide ion is a reducing agent, the strongest ability raises down the group.
• The heat resistance of the material, the object by the deformation under the capacity of temperature, the deformation is less, the stability is more. Using thermo gravimetric analysis (TGA), the stability of polymer is determined.
