(b) Among halide ions, iodide is the most powerful reducing agent
(c) Fluorine is the only halogen that does not show a variable oxidation state
(d) $HOCl$ is a stronger acid than $HOBr$

Solution:
- (a) $F$ is more electronegative than $Cl$ therefore $HF$ bond is stronger than $HCl$ and hence proton is not given off easily. Hence HF is the weakest hydrohalic acid.
