Rank of Compounds Based on Relative Br\u00f8nsted Acidity:<\/strong><\/h3>\n\n\n\n

H-I > H-F > H-SH > H-NH\u2082 > H-CH\u2083<\/strong><\/p>\n\n\n\n

Explanation:<\/strong><\/h3>\n\n\n\n

1. Definition of Br\u00f8nsted Acidity:<\/strong> Br\u00f8nsted acidity refers to the tendency of a compound to donate a proton (H\u207a). A stronger Br\u00f8nsted acid dissociates more readily in solution, yielding a higher concentration of H\u207a ions.<\/p>\n\n\n\n

2. Factors Influencing Acidity:<\/strong><\/p>\n\n\n\n

    \n
  • Bond Strength:<\/strong> The strength of the bond between hydrogen and the attached atom significantly affects acidity. A weaker bond allows easier release of H\u207a.<\/li>\n\n\n\n
  • Electronegativity:<\/strong> Higher electronegativity stabilizes the conjugate base by better accommodating the negative charge.<\/li>\n\n\n\n
  • Polarizability:<\/strong> Larger atoms better stabilize the negative charge due to their greater polarizability.<\/li>\n<\/ul>\n\n\n\n

    Compound Analysis:<\/strong><\/h3>\n\n\n\n
      \n
    1. H-I (Strongest Acid):<\/strong>\n
        \n
      • Bond Strength:<\/strong> Iodine is a large atom, resulting in a weak H-I bond.<\/li>\n\n\n\n
      • Polarizability:<\/strong> The conjugate base (I\u207b) is highly stable due to its large size and ability to delocalize charge.<\/li>\n\n\n\n
      • Conclusion:<\/strong> H-I is the strongest acid.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • H-F:<\/strong>\n
          \n
        • Electronegativity:<\/strong> Fluorine is the most electronegative element, stabilizing the conjugate base (F\u207b).<\/li>\n\n\n\n
        • Bond Strength:<\/strong> The H-F bond is very strong, which slightly reduces acidity compared to H-I.<\/li>\n\n\n\n
        • Conclusion:<\/strong> H-F is the second strongest acid.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • H-SH:<\/strong>\n
            \n
          • Polarizability:<\/strong> Sulfur, being larger than oxygen, stabilizes the conjugate base (SH\u207b) better than H-NH\u2082.<\/li>\n\n\n\n
          • Conclusion:<\/strong> Moderate acidity.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • H-NH\u2082:<\/strong>\n
              \n
            • Electronegativity:<\/strong> Nitrogen is less electronegative than oxygen or fluorine, making NH\u2082\u207b less stable.<\/li>\n\n\n\n
            • Conclusion:<\/strong> Weak acid.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
            • H-CH\u2083 (Weakest Acid):<\/strong>\n
                \n
              • Bond Strength:<\/strong> The H-C bond is very strong.<\/li>\n\n\n\n
              • Conjugate Base:<\/strong> CH\u2083\u207b is highly unstable due to poor charge stabilization.<\/li>\n\n\n\n
              • Conclusion:<\/strong> Weakest acid.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
                \n\n\n\n

                Summary:<\/h3>\n\n\n\n

                The ranking is based on bond strength, electronegativity, and polarizability, with H-I being the strongest Br\u00f8nsted acid and H-CH\u2083 the weakest.<\/p>\n\n\n\n
