- What is the formal charge of \(\ce{N}\) in the following dot structure?
. N / \\ O O
Hint: Number of electrons around N = 1 + (6/2)
Skill: Evaluate the formal charge of any atom of any dot structure.
What is the formal charge for the resonance structure having the odd electron on the oxygen atom? - Hint: Bond order = 1.5
Discussion: Four resonance structures have been given, and all indicate a bond order of 1.5 for \(\ce{[O-N=O]}\) <=> \(\ce{[O=N-O]}\).
- Hint: Huum! This sounds like a real-world problem.
Skill: Solving real-world problems requires you to know what information to look for before the problem is solvable. This is one of those problems.
In an exercise or an open-book test, we can ask you to evaluate the lattice energy of a salt, and you need to find the various data. Since the CAcT quiz is an open-book test, this type of problem should have been given, but you will not have this type of problem in this quiz.
