Answer» `K_2O LT CAO lt SiO_2 lt CuO lt CO_2 lt N_2O_5` `K_2O lt CaOlt CuO lt SiO_2 lt CO_2 lt N_2O_5` `CaO lt K_2Olt SiO_2 lt CuO lt CO_2 lt N_2O_5` `K_2O ltSiO_2 lt CaO lt CuO lt CO_2 lt N_2O_5` Solution :As difference in ELECTRONEGATIVITY between element and oxygen INCREASES, ACIDIC character decreases and basic character increases.
