Question:
HF, HCl, HBr, HI (thermal stability)
HF, HCl, HBr, HI (thermal stability)
Show Hint
Thermal stability of hydrogen halides decreases as bond strength weakens down the group.
Updated On: Mar 4, 2025
Show Solution
Verified By Collegedunia
Solution and Explanation
Increasing Order of Thermal Stability: Thermal stability of hydrogen halides (HX) decreases down the group due to decreasing bond strength
(H-F) being the strongest and (H-I) the weakest. \[ HI < HBr < HCl < HF \]
