Detailed Solution

Basicity is inversely proportional to the electronegative character of a molecule. On increasing the oxidation states, the acidity of a molecule increases or basicity of a molecule decreases. In FeO, the oxidation state of Fe is +2 and in Fe₂O₃, the oxidation state of Fe is +3. Therefore, FeO is more basic than Fe₂O₃.
