Nitrite (NO₂^-)is an important nutrient in the eutrophic zone of the ocean.Which of the following is the best set of resonance structures for this ion?

Question

Quizplus · Accepted Answer

The correct resonance structures should reflect the delocalization of the negative charge on the oxygen atoms in the ion. Option A has a double bond between each of the nitrogens and one of the oxygen atoms, and an additional negative charge on the other oxygen atom, making it the most stable and accurate representation of the ion. Option B has all single bonds, which implies that the negative charge is localized on the oxygen atoms, making it less accurate. Option C has a double bond between one nitrogen and one oxygen, but not the other, which does not accurately represent the delocalization of charge. Option D has two negative charges on one nitrogen atom, which is highly unlikely due to the electronegativity difference between nitrogen and oxygen. Therefore, option A is the best choice.
