# Questions on Neutral oxides

Neutral oxides, are non metal oxides which are neither acidic nor basic. I have noticed a pattern for neutral oxides which I am unsure actually holds true.

$$\ce{CO}$$, $$\ce{H2O}$$, $$\ce{NO}$$ and $$\ce{N2O}$$ are examples of neutral oxides. It seems that neutral oxides will always have 1 oxygen atom. While non metal oxides with more than 1 oxygen atom seems to always be acidic oxide. ($$\ce{CO2}$$, $$\ce{SO3}$$, $$\ce{SO2}$$ and $$\ce{P4O10}$$).

Is this a coincidence? Are there any neutral oxides with more than one oxygen atom?

• This is just a coincidence. Besides, H2O is not neutral; it is both acidic and basic, which might seem to be the same, but in fact is quite different. – Ivan Neretin Feb 14 at 12:31
• And, $\ce{NO}$ is not just $\ce{NO}$. It will contain a little dimer, $\ce{N2O2}$, which is still neutral. – Oscar Lanzi Feb 14 at 13:37
• Hmm, Since N2O2 is a neutral oxide, then it disproves the "all neutral oxides have 1 oxygen atom". However, the empirical formula of N2O2 is NO. Is C2O2 and N4O2 neutral also? If they are neutral also, maybe the empirical formula of a neutral oxide will always have oxygen with a ratio of 1 to the other components. – Bryan Foong Zhi Chuan Feb 14 at 14:41
• Do not get hung up on this. $\ce{Cl2O}$ is acidic. – Oscar Lanzi Feb 14 at 14:50
