The correct order of the thermal stability of hydrogen halides (H -X) is
HI>HBr>HCl>HF
HF>HCl>HBr>HI
HCl<HF<HBr<HI
HI>HCl<HF<HBr
HF > HCl > HBr > HI (Thermal stability).
The correct order of thermal stability of hydrogen halides (H – X) is
The correct order of boiling points of HF , HCl , HBr and HI is
