Multiple Choice

The option(s) with only amphoteric oxides is (are):

A$$Cr_{2}O_{3}, BeO, SnO, SnO_{2}$$
Correct Answer
B$$Cr_{2}O_{3}, CrO, SnO, PbO$$
C$$ZnO, Al_{2}O_{3}, PbO, PbO_{2}$$
Correct Answer
D$$NO, B_{2}O_{3}, PbO, SnO_{2}$$

Solution

The options with only amphoteric oxides are
$$\displaystyle Cr_{2}O_{3}, BeO, SnO, SnO_{2}$$
$$\displaystyle ZnO, Al_{2}O_{3}, PbO, PbO_{2}$$

However, $$\displaystyle \: B_{2}O_{3} $$ is acidic oxides, $$CrO$$ is basic oxide and $$NO$$ is neutral.

Note: Amphoteric oxides react with acids as well as bases.
