Question

Which of the following oxides is acidic in nature?

• A. \( GeO_2 \)
• B. \( CO \)
• C. \( PbO_2 \)
• D. \( SnO \)

Hint:

- Acidic oxides are generally formed by nonmetals or metalloids in higher oxidation states. - Amphoteric oxides exhibit both acidic and basic behavior. - Neutral oxides do not react with acids or bases (e.g., CO, NO).

Answer 1

The Correct Option is A

\(GeO_2\) (Germanium dioxide) is acidic in nature.

Oxides of metalloids, like germanium, tend to be amphoteric or weakly acidic. As you move across the periodic table from left to right, the metallic character decreases, and the nonmetallic character increases. Elements with higher nonmetallic character tend to form acidic oxides. While germanium is a metalloid, it's on the right side of the metalloid region, so its oxide exhibits acidic properties.
