Vedclass · Answer

(C) To determine where all three effects (inductive,mesomeric,and hyperconjugation) operate,we analyze the structures:$A$. Chlorocyclohexane: Shows inductive effect ($-I$ of $Cl$) but lacks conjugation for mesomeric or hyperconjugation.$B$. $1,2$-Dimethylcyclohex-$1$-ene: Shows inductive effect and hyperconjugation (due to $\alpha$-hydrogens on the methyl groups attached to the double bond),but lacks a mesomeric effect.$C$. $1-(2$-Methylcyclohex-$1$-en-$1$-yl$)$ethan-$1$-one: $1$. Inductive effect: The carbonyl group $(C=O)$ and the alkyl groups exert inductive effects.$2$. Mesomeric effect: The carbonyl group is conjugated with the double bond of the cyclohexene ring,allowing for resonance (mesomeric effect).$3$. Hyperconjugation: The methyl group attached to the double bond has $\alpha$-hydrogens,allowing for hyperconjugation.$D$. Benzene: Shows mesomeric effect (resonance) and inductive effect (if substituted),but does not exhibit hyperconjugation.Thus,option $C$ is the correct molecule where all three effects operate.

List-$I$	List-$II$
$(A)$ Resonance	$(I)$ $C=C + H^+ \rightarrow C^+-C-H$
$(B)$ Inductive effect	$(II)$ $H-CH_2-CH_2^+ \leftrightarrow H-CH_2=CH_2^+$
$(C)$ Electromeric effect	$(III)$ $C_6H_6$
$(D)$ Hyperconjugation	$(IV)$ $CH_3-Z \rightarrow CH_3^- + Z^+$
	$(V)$ $CH_3-CH_2-CH_2Cl$

In which of the following molecules do all the effects namely inductive,mesomeric and hyperconjugation operate?
