The partial structure showing the connection of atoms in niflumic acid is shown below. Complete the Lewis structure (including lone pairs), give the number of σ and π bonds, and determine the hybridization of C, N, and O atoms.

• A. 23 σ bonds & 14 π bonds
  Hybridization:
  C, N, and O containing double bonds: sp²
  C, N, and O containing only single bonds: sp³
• B. 23 σ bonds & 14 π bonds
  Hybridization:
  N containing double bond: sp
  N containing only single bonds, C and O containing double bonds: sp²
  C, N, and O containing only single bonds: sp³
• C. 30 σ bonds & 7 π bonds
  Hybridization:
  C, N, and O containing double bonds: sp²
  C, N, and O containing only single bonds: sp³
• D. 30 σ bonds & 7 π bonds
  Hybridization:
  N containing double bond: sp
  N containing only single bonds, C and O containing double bonds: sp²
  C, N, and O containing only single bonds: sp³

Answer: (C)
