which is the iupac name for no?
nitric oxide
binitrogen oxide
dinitrogen dioxide
nitrogen monoxide

Explanation:

IUPAC naming for covalent compounds uses prefixes to indicate the number of each atom: "mono-" for 1 (omitted for the first element if only one atom). For NO, there is 1 nitrogen atom and 1 oxygen atom, so it is named nitrogen monoxide. The other options are incorrect: "nitric oxide" is a common name, not IUPAC; "binitrogen oxide" and "dinitrogen dioxide" do not match the 1:1 atom ratio in NO.

Answer:

nitrogen monoxide
