Inductive polarization of X-H Bond and Resonance Stabilization of A-

• Nitrous acid < Nitric acid

• Hypochlorous acid < Chlorous acid < Chloric acid < Perchloric acid

• Acetic acid (CH3COOH)

• The more polarized the weaker the X-H bond, the more stronger the acid

• The more resonance stabilized the A-, the stronger the acid
