Vedclass · Answer

(B) In $C_{6}H_{5}NH_{2}$,$C_{6}H_{5}OH$,and $C_{6}H_{5}Cl$,the substituent attached to the benzene ring has at least one lone pair of electrons,which can participate in resonance with the $\pi$-system of the ring.In $C_{6}H_{5}NH_{3}^{+}$,the nitrogen atom has four bonds and no lone pair of electrons available for resonance.As shown in the figure,structure $(II)$ is not a valid resonance contributor because the nitrogen atom would have $10$ valence electrons,which violates the octet rule.Therefore,$C_{6}H_{5}NH_{3}^{+}$ does not exert a resonance effect.

Which of the following species does not exert a resonance effect?
