Question

Among the following the neutral oxide is

• A. $GeO$
• B. $CO$
• C. $GeO_2$
• D. $CO_2$

Hint:

{Neutral Oxides:} $CO$ (Carbon monoxide), $NO$ (Nitric oxide), $N_2O$ (Nitrous oxide). Memorize this trio.

Answer 1

The Correct Option is B

Step 1: Analyze the Nature of Oxides:

• $GeO$: Germanium(II) oxide is acidic/amphoteric in nature.
• $CO$: Carbon monoxide is a well-known neutral oxide (it reacts with neither acids nor bases to form salts).
• $GeO_2$: Germanium(IV) oxide is distinctly acidic (and slightly amphoteric).
• $CO_2$: Carbon dioxide is an acidic oxide (forms carbonic acid with water).

Step 2: Identify Neutral Oxides:
Common neutral oxides are $CO$, $NO$, and $N_2O$.
Step 3: Conclusion:
$CO$ is the neutral oxide.
