Question: The acidic, basic and amphoteric oxides, respectively, are:
$\mathrm{Na}_{2} \mathrm{O}, \mathrm{SO}_{3}, \mathrm{Al}_{2} \mathrm{O}_{3}$
$\mathrm{Cl}_{2} \mathrm{O}, \mathrm{CaO}, \mathrm{P}_{4} \mathrm{O}_{10}$
$\mathrm{N}_{2} \mathrm{O}_{3}, \mathrm{Li}_{2} \mathrm{O}, \mathrm{Al}_{2} \mathrm{O}_{3}$
$\mathrm{MgO}, \mathrm{Cl}_{2} \mathrm{O}, \mathrm{Al}_{2} \mathrm{O}_{3}$
Correct Option: , 3
Solution:
Generally, non-metal oxides are acidic in nature and metal oxides are basic in nature, $\mathrm{Al}_{2} \mathrm{O}_{3}$ is amphoteric.
