Question 12

Two Period 3 oxides, D D\,D and EEE, are tested:

  • Oxide D D\,D is a white solid that reacts vigorously with water to produce a strongly acidic solution (pH=1−2\text{pH} = 1-2pH=1−2).
  • Oxide E E\,E is a crystalline solid that is insoluble in water and does not react with hydrochloric acid, but reacts when heated with concentrated sodium hydroxide solution.

Which option correctly identifies oxides D D\,D and E E\,E along with their respective crystal structures?

Oxide DDD is P4O10\text{P}_4\text{O}_{10}P4​O10​ (simple molecular); Oxide EEE is SiO2\text{SiO}_2SiO2​ (giant covalent)

Oxide DDD is SO3\text{SO}_3SO3​ (simple molecular); Oxide EEE is Al2O3\text{Al}_2\text{O}_3Al2​O3​ (giant covalent)

Oxide DDD is P4O10\text{P}_4\text{O}_{10}P4​O10​ (giant covalent); Oxide EEE is SiO2\text{SiO}_2SiO2​ (simple molecular)

Oxide DDD is SO2\text{SO}_2SO2​ (simple molecular); Oxide EEE is SiO2\text{SiO}_2SiO2​ (giant ionic)
