Among Al2O3,SiO2,P2O3\mathrm{Al}_2 \mathrm{O}_3, \mathrm{SiO}_2, \mathrm{P}_2 \mathrm{O}_3 and SO2\mathrm{SO}_2 the correct order of acid strength is

Options

  1. ASO2<P2O3<SiO2<Al2O3\mathrm{SO}_2 < \mathrm{P}_2 \mathrm{O}_3 < \mathrm{SiO}_2 < \mathrm{Al}_2 \mathrm{O}_3
  2. BAl2O3<SiO2<P2O3<SO2\mathrm{Al}_2 \mathrm{O}_3 < \mathrm{SiO}_2 < \mathrm{P}_2 \mathrm{O}_3 < \mathrm{SO}_2
  3. CAl2O3<SiO2<SO2<P2O3\mathrm{Al}_2 \mathrm{O}_3 < \mathrm{SiO}_2 < \mathrm{SO}_2 < \mathrm{P}_2 \mathrm{O}_3
  4. DSiO2<SO2<Al2O3<P2O3\mathrm{SiO}_2 < \mathrm{SO}_2 < \mathrm{Al}_2 \mathrm{O}_3 < \mathrm{P}_2 \mathrm{O}_3

Correct answer

B. Al2O3<SiO2<P2O3<SO2\mathrm{Al}_2 \mathrm{O}_3 < \mathrm{SiO}_2 < \mathrm{P}_2 \mathrm{O}_3 < \mathrm{SO}_2
