. Which one of the following statements is not true

(a) Among halide ions, iodide is the most powerful reducing agent.

(b) Fluorine is the only halogen that does not show a variable oxidation state.

(c) HOCl is a stronger acid than HOBr.

(d) HF is a stronger acid than HCl.

Best Answer

Correct Option is (d)

HF is a weaker acid because the strength of an acid is determined by how completely that acid will dissociate.

Since the bond between HF is stronger than the bond between HCl, HCl will more completely dissociate which makes it a stronger acid.
