Step 1:I'll solve this chemistry nomenclature problem following the specified formatting guidelines:
Step 2:: Identify the chemical formula
The chemical formula is $$HNO_{2}$$, which contains:
- 1 hydrogen atom (H) - 1 nitrogen atom (N) - 2 oxygen atoms (O)
Step 3:: Determine the acid naming convention
Since this is an acid with oxygen (an oxoacid), we use the "-ous" suffix for the acid name.
Step 4:: Name the acid
The base name comes from the central atom's element (nitrogen), so we use "nitro-" as the root. For an acid with fewer oxygen atoms, we use the "-ous" suffix.
Step 5:: Combine the naming rules
Putting the rules together, the correct name is: Nitrous acid
Final Answer
Key Insights: - HNO_{2} follows the oxoacid naming convention - The "-ous" suffix indicates fewer oxygen atoms compared to the "-ic" acid form - The name directly reflects the chemical composition and structure
