What is the correct name for the molecular compound with the formula N_2O_3?

• A. Nitrogen trioxide
• B. Nitrogen dioxide
• C. Dinitrogen trioxide
• D. Dinitrogen pentoxide

Answer: (C)

Verified step by step guidance

1. Identify the elements present in the molecular formula N_2O_3, which are nitrogen (N) and oxygen (O).
2. Recognize that molecular compounds are named using prefixes to indicate the number of atoms of each element present in the compound.
3. Recall the common prefixes for numbers: 1 = mono-, 2 = di-, 3 = tri-, 4 = tetra-, 5 = penta-, etc.
4. Apply the prefixes to the elements: since there are 2 nitrogen atoms, use 'dinitrogen'; since there are 3 oxygen atoms, use 'trioxide'.
5. Combine the prefixes and element names to form the correct name: 'Dinitrogen trioxide'.
