Vedclass · Answer

(C) Groups that exhibit the negative resonance $(-R)$ effect are those that withdraw electron density from the conjugated system. These groups typically contain multiple bonds with electronegative atoms.$(A)$ Formyl $(-CHO)$: $-C(=O)H$ ($-R$ effect)$(B)$ Amino $(-NH_2)$: $+R$ effect due to lone pair on $N$.$(C)$ Alkoxy $(-OR)$: $+R$ effect due to lone pair on $O$.$(D)$ Cyano $(-CN)$: $-C \equiv N$ ($-R$ effect)$(E)$ Nitro $(-NO_2)$: $-NO_2$ ($-R$ effect)Therefore,$A, D,$ and $E$ exhibit the $-R$ effect.

From the following,identify the groups that exhibit negative resonance $(-R)$ effect when attached to a conjugated system: $(A)$ formyl,$(B)$ amino,$(C)$ alkoxy,$(D)$ cyano,$(E)$ nitro
