I am trying to make out why this is true. I have seen the related questions but they are about the neutral hydrides and not charged ones. My working was that the order of acidity should be the reverse order of the basicity of their conjugate bases. cruises to bahamas from miami 2 nights WebAug 14, 2024 · On moving down the group, the atomic size increases, electronegativity decreases and metallic character increases. All these elements form two types of oxides: E 2 O 3 and E 2 O 5. The oxide in the higher oxidation state of the elements is more acidic than that of lower oxidation state. Oxides of nitrogen and phosphorus are acidic.

WebJun 18, 2024 · As a result, acid strengths of binary hydrides increase as we go down a column of the periodic table. For example, the order of acidity for the binary hydrides of Group 16 elements is as follows, with p K a values in parentheses: (16.10.1) H 2 O ( 14.00 = p K w) < H 2 S ( 7.05) < H 2 S e ( 3.89) < H 2 T e ( 2.6) Stability of the Conjugate Base WebThe structure of H2S is as follows And the structure of other hydrides as similar. But here’s the surprise for those people. The answer is that the acidic nature of the hydrides of group 16 increases down the group as we move down the group.
