Which one of the following is the correct order of increasing acidic nature of oxides?

Question

Vimal Swarnkar · Accepted Answer

(c) Al₂O₃ <SiO₂ < SO₃ < Cl₂O₇. Across period 3, oxides go from basic → amphoteric → acidic as the oxidation state and electronegativity of the element rise: Al₂O₃ (amphoteric) < SiO₂ (weakly acidic) < SO₃ < Cl₂O₇ (strongest, gives HClO₄) → (c).

Answer

(a) SiO₂ < Al₂O₃ <SO₃ < Cl₂O₇

Answer

(b) SiO₂ < SO₃ <Al₂O₃ < Cl₂O₇

Answer

(d) Cl₂O₇ < SiO₂ < SO₃ < Al₂O₃
