Which of the following does not show a resonance effect

Question

Which of the following does not show a resonance effect (A) C6H5OH (B) C6H5Cl (C) C6H5NH2 (D) C6H5NH3

Tardigrade Admin · Accepted Answer

C6H5 overset+NH3 (protonated aniline) does not show resonance effect. The nitrogen of protonated aniline does not have any non-bonding electrons that can be delocalised. Whereas all other options have non-bonding electrons that can be delocalised.

Q. Which of the following does not show a resonance effect

$C_{6} H_{5} O H$

$C_{6} H_{5} Cl$

$C_{6} H_{5} N H_{2}$

$C_{6} H_{5} N H_{3}$

$C_{6} H_{5} N + H_{3}$ (protonated aniline) does not show resonance effect. The nitrogen of protonated aniline does not have any non-bonding electrons that can be delocalised. Whereas all other options have non-bonding electrons that can be delocalised.
