Which is the stronger acid: H-F or H-I?
 
  A) H-F, because the electronegativity of fluorine is higher than that of iodine making the H-F bond more polar and more likely to release the hydrogen ion to solution.
  B) H-F, because acid strength for binary acids decreases down the group of the periodic table.
  C) H-I, because iodine releases the hydrogen in order to form (s) at room temperature.
  D) H-I, because the H-I bond is weaker and so it is easier to break to form hydrogen ions.
