JEE Main Chemistry question

The correct order of acidic nature (of common period-2/period-3 oxides) is:

(A)Na_2O<MgO<Al_2O_3<SiO_2<P_4O_{10}<SO_3<Cl_2O_7Correct
(B)Cl_2O_7<SO_3<P_4O_{10}<SiO_2<Al_2O_3<MgO<Na_2O
(C)Al_2O_3<Na_2O<MgO<SiO_2<P_4O_{10}<SO_3<Cl_2O_7
(D)Na_2O<Al_2O_3<MgO<SiO_2<SO_3<P_4O_{10}<Cl_2O_7

Answer: (A)

Solution

The source's original printed options for this item were badly corrupted by an OCR/page-layout line-wrap (an internally inconsistent oxide list merged with an unrelated, incomplete question on basic-oxide strength down a group); rather than preserve that unreliable reconstruction, this item has been rewritten around
