Question

which is the correct name for the compound n₂o₄?
a) dinitrogen quadoxide
b) nitrogen oxide
c) tetranitrogen dioxide
d) dinitrogen tetroxide

Explanation:

For naming binary covalent compounds (compounds between non - metals), we use prefixes to indicate the number of each atom. The prefix for 2 is "di -" and for 4 is "tetra -". The first element is named with its element name and the prefix (if there is more than one atom), and the second element is named with its root (ox - for oxygen) and the suffix "-ide" along with the prefix. In \(N_2O_4\), there are 2 nitrogen atoms (\(N_2\)) so "dinitrogen" and 4 oxygen atoms (\(O_4\)) so "tetroxide".

Answer:

D. dinitrogen tetroxide
