p-nitro-N, N - dimethylaniline cannot be represented by the resonating structures
- A I and II
- B II and IV
- C I and III
- D III and IV
Answer & Solution
Correct Answer
(B) II and IV
Step-by-step Solution
Detailed explanation
Both the structures are impossible as \(\mathrm{N}^{\circ}\) is pentavalent and we known that \(\mathrm{N}\) can not expand its valency beyond 4 due to absence of vacant d-orbitals in its valence shell.
