Cyclopentanone reacting with $OH^-/\Delta$ to form a self-aldol condensation product.

Vedclass · Answer

(B) Let's analyze each reaction:$A$: The reaction of $2$-chlorocyclohexane with $C_2H_5OH$ (a weak nucleophile/solvent) proceeds via an $S_N1$ mechanism,which involves a carbocation intermediate. This can lead to rearrangement or substitution at different positions,making the products shown plausible.$B$: The reaction of cyclopentanone with $OH^-/\Delta$ is an aldol condensation,which typically forms a $\beta$-hydroxy ketone followed by dehydration to an $\alpha,\beta$-unsaturated ketone. The product shown is not the standard aldol condensation product of cyclopentanone.$C$: The reduction of an internal alkyne with $Na/liq. NH_3$ (Birch-type reduction) is a stereospecific reaction that yields the $trans$-alkene. This is correct.$D$: The reaction of the bicyclic dichloride with $MeOH$ is a solvolysis reaction. Given the structure,it can undergo substitution to form the methoxy product.Therefore,option $B$ is the $INCORRECT$ reaction.

List-$I$ (Reactions)	List-$II$ (Reagents)
$(A)$ $CH_3(CH_2)_5COOC_2H_5 \rightarrow CH_3(CH_2)_5CHO$	$(I)$ $CH_3MgBr, H_2O$
$(B)$ $C_6H_5COC_6H_5 \rightarrow C_6H_5CH_2C_6H_5$	$(II)$ $Zn(Hg)$ and conc. $HCl$
$(C)$ $C_6H_5CHO \rightarrow C_6H_5CH(OH)CH_3$	$(III)$ $NaBH_4, H^+$
$(D)$ $CH_3COCH_2COOC_2H_5 \rightarrow CH_3CH(OH)CH_2COOC_2H_5$	$(IV)$ $DIBAL-H, H_2O$
