What is the correct name for the molecular compound N_2O_5?
A
nitrogen dioxide
B
nitrogen pentoxide
C
dinitrogen dioxide
D
dinitrogen pentoxide
Verified step by step guidance1
Identify the elements present in the compound N_2O_5: nitrogen (N) and oxygen (O).
Determine the number of atoms of each element: 2 nitrogen atoms and 5 oxygen atoms.
Recall the naming rules for molecular (covalent) compounds: use prefixes to indicate the number of atoms of each element (mono-, di-, tri-, tetra-, penta-, etc.).
Apply the prefixes to the elements: 'di-' for 2 nitrogens and 'penta-' for 5 oxygens, resulting in 'dinitrogen pentoxide'.
Note that the second element's name ends with '-ide', so oxygen becomes 'oxide', completing the name as 'dinitrogen pentoxide'.
