Which one of the following statement is not true?

Options

  1. AAmong halide ions, iodide is the most powerful reducing agent
  2. BFluorine is the only halogen that does not show a variable oxidation state
  3. CHOCl is a stronger acid that HOBr
  4. DHF is a stronger acid than HCl

Correct answer

D. HF is a stronger acid than HCl

Step-by-step solution

HCl is a stronger acid than HF because fluorine is more electronegative than chlorine. Hence, it does not lose H ⁺ easily. Caution H F is a weak acid because the bond between Hydrogen and Fluorine is so short. It is more difficult for the bond to be broken, so it will not completely dissociate in water.
