What is the correct name for the molecular compound with the formula N_2O?
A
Nitrogen dioxide
B
Nitrous oxide
C
Dinitrogen oxide
D
Dinitrogen monoxide
Verified step by step guidance1
Identify the elements present in the molecular formula N_2O: nitrogen (N) and oxygen (O).
Determine the number of atoms of each element: there are 2 nitrogen atoms and 1 oxygen atom.
Recall the naming rules for molecular (covalent) compounds: use prefixes to indicate the number of atoms (mono-, di-, tri-, etc.), and the second element's name ends with '-ide'.
Apply the prefixes to the elements: 'di-' for two nitrogens and 'mono-' for one oxygen. Since 'mono-' is often shortened to 'mon-' before vowels, the oxygen part becomes 'monoxide'.
Combine the parts to form the correct name: 'Dinitrogen monoxide'.
