Vedclass · Answer

(D) The given structures are tautomers of bicyclo[$2.2$.$1$]heptan$-2-$one.Structure $(II)$ is the keto form,which is generally more stable than the enol forms $(I)$ and $(III)$.Structure $(I)$ contains a double bond at the bridgehead carbon,which violates Bredt's rule,making it highly unstable.Structure $(III)$ is a stable enol form where the double bond is not at the bridgehead.Therefore,the stability order is $(II) > (III) > (I)$.

List-$I$ (Pair of Compounds)	List-$II$ (Isomerism)
$A$. $n$-propanol and Isopropanol	$(I)$ Metamerism
$B$. Methoxypropane and ethoxyethane	$(II)$ Chain Isomerism
$C$. Propanone and propanal	$(III)$ Position Isomerism
$D$. Neopentane and Isopentane	$(IV)$ Functional Isomerism

The correct stability order of the given tautomers is:
