Question

Which of the following is the most basic oxide?

A

Al2O3\text{Al}_2\text{O}_3

B

Sb2O3\text{Sb}_2\text{O}_3

C

Bi2O3\text{Bi}_2\text{O}_3

D

SeO2\text{SeO}_2

Step-by-Step Solution

As we move down a group in the periodic table, the metallic character of elements increases, which in turn increases the basic character of their oxides. Among the given options:

  1. Al2O3\text{Al}_2\text{O}_3 (Aluminium oxide) and Sb2O3\text{Sb}_2\text{O}_3 (Antimony trioxide) are amphoteric oxides.
  2. SeO2\text{SeO}_2 (Selenium dioxide) is an oxide of a non-metal, hence it is acidic.
  3. Bi2O3\text{Bi}_2\text{O}_3 (Bismuth(III) oxide) is an oxide of bismuth, a typical metal located at the bottom of Group 15. Therefore, it is the most basic oxide among the given choices.
