Which of the following species does not exert a resonance effect?
- A \(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2}\)
- B \(\mathrm{C}_{6} \mathrm{H}_{5}{ }^{+} \mathrm{NH}_{3}\)
- C \(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{OH}\)
- D \(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{Cl}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{C}_{6} \mathrm{H}_{5}{ }^{+} \mathrm{NH}_{3}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{C}_{6} \mathrm{H}_{5}+\mathrm{NH}_{3}\) does not exert a resonance effect because all the electron pairs of nitrogen are involved in bond formation. Hence, no lone pair is present on nitrogen for resonance.
