Question

In writing resonance structures, drawing a pentavalent nitrogen atom automatically invalidates the structure. What is the fundamental chemical reason for this rule?

Answer: B

💡 Solution & Explanation

Second-period elements (C, N, O, F) can accommodate a maximum of 8 valence electrons (4 bonds). Because nitrogen has no accessible d-orbitals in its valence shell, it can NEVER form 5 bonds.
