Question
Acid Structure and Relative Acidity The strength of an acid, HA, is often determined by the strength and polarity of the H-A bond. In general, a weaker and more polar bond leads to a stronger acid. For binary acids of elements in the same group of the periodic table, the H-A bond strength decreases down the group, so acidity increases. For binary acids of elements in the same row of the periodic table, the polarity of the H-A bond increases from left to right (as the electronegativity of A increases), so acid strength increases. For oxoacids, acid strength increases with the oxidation number of the central atom. If the oxidation number is the same, acid strength increases with the electronegativity of the central atom. Part A Rank the following compounds in order decreasing acid strength using periodic trends. Rank the acid strength from strongest to weakest. To rank items as equivalent, overlap them. ▸ View Available Hint(s) BH₁ HBr HCI H₂S Greatest acid strength The correct ranking cannot be determined. Submit Reset Help Weakest acid strength
