Two bonds $\mathrm{N}=\mathrm{O}$ and $\mathrm{N}-\mathrm{O}$ in $\mathrm{H}_3 \mathrm{CNO}_2$ are of same bond length due to

• A

  inductive effect
• B

  hyperconjugation
• C

  electromeric effect
• Correct answer
  D

  resonance effect

Solution

Two bonds $\mathrm{N}=\mathrm{O}$ and $\mathrm{N}-\mathrm{O}$ in $\mathrm{H}_3 \mathrm{CNO}_2$ are of same bond length due to resonance effect.

Hence, the correct answer is option: 'D'.
