Select the correct statement(s) about the hydrogen halides.

AThe thermal stability of $HI$ is greater than that of $HCl$ .
B $HF$ has the highest boiling point among the hydrogen halides.
C $HCl$ is a stronger acid than $HF$ in water.
D $HI$ is a stronger reducing agent than $HBr$ .

Answer: B, C, D

A, B and D are correct: reducing power rises and thermal stability falls from HF to HI, HF is hydrogen bonded, and HCl ionises more readily than HF. C is false, since the weaker H-I bond makes HI the least stable.
