1.	Which of the following statement is incorrect ?A. Oxide of aluminium `(Al_(2)O_(3))` and arsenic `(As_(2)O_(3))` are amphoteric.B. Oxide of chlorine `(Cl_(2)O_(7))` is less acidic than oxide of nitrogen `(N_(2)O_(5))`.C. Oxide of carbon `(CO_(2))` is more acidic than oxide of silica `(SiO_(2))`.D. The correct increasing order of basic character of various oxides is `H_(2)O lt CuO lt MgO lt CaO`.
Answer» Correct Answer - B `overset(+7)(Cl)_(2)O_(7)` having higher oxidation state is more acidic than `overset(+5)(N_(2))O_(5)` having lower oxidation state.
