Answer
C. dinitrogen trioxide
Explanation
The IUPAC (International Union of Pure and Applied Chemistry) nomenclature system is used globally to assign names to chemical compounds which follow a regular, predefined set of rules. According to IUPAC nomenclature, compounds of nitrogen and oxygen which do not contain any charged particles (like in this case, N2O3) are termed using prefixes to denote the number of atoms in each element:* Mono- is used for one atom;* Di- is for two;* Tri- is for three and so on.Prefixes are attached to the elements in sequence from left to right. The order of the elements within the compound determines the prefixes and element name necessary. Therefore, looking at N2O3:* N, which denotes Nitrogen, has a prefix of di- for two atoms, hence becomes dinitrogen;* O, which is Oxygen, has a prefix of tri- for three atoms, thus becomes trioxide. So, the correct IUPAC name would be dinitrogen trioxide since it reflects the composition accurately.The other given options: Nitric oxide and Nitrous oxide are actual compounds with the formulae NO and N2O tracking back to Nitrogen with mono/one Oxygen and Dinitrogen with mono/one Oxygen respectively and trioxygen dinitride is incorrect as the sequence of Element-quantity does not match the order in the compound (N2O3).
