Vedclass · Answer

(D) Resonance requires a conjugated system,which involves alternating single and multiple bonds or the presence of lone pairs adjacent to a double bond.$A$: $CH_3-CH_2-CH_2-CONH_2$ exhibits resonance due to the conjugation between the lone pair on the nitrogen atom and the carbonyl group $(C=O)$.$B$: $C_6H_5CH_2OH$ (Benzyl alcohol) does not exhibit resonance involving the $-CH_2OH$ group because the $-CH_2-$ group acts as an insulator,preventing the lone pair on the oxygen from conjugating with the benzene ring.$C$: $CH_3-CH_2-OCH=CH_2$ exhibits resonance due to the conjugation between the lone pair on the oxygen atom and the $C=C$ double bond.$D$: $CH_3-CH_2-CH=CH-CH_2-NH_2$ is a non-conjugated system where the double bond and the lone pair on the nitrogen are separated by $sp^3$ hybridized carbon atoms,thus it does not exhibit resonance.
